Which will increase the rate of chemical reaction quizlet?

Which will increase the rate of chemical reaction quizlet?

Describe three ways to increase the rate of a chemical reaction. increase temperature by adding heat, increases the surface area of the reactants, increase the concentration of the reactants, or add a catalyst.

Who slows down oxygen speed?

Nitrogen

What are the different types of catalyst?

Catalysts are primarily categorized into four types. They are (1) Homogeneous, (2) Heterogeneous (solid), (3) Heterogenized homogeneous catalyst and (4) Biocatalysts.

What are the 3 types of catalysis?

Catalysts and their associated catalytic reactions come in three main types: homogeneous catalysts, heterogeneous catalysts and biocatalysts (usually called enzymes). Less common but still important types of catalyst activities include photocatalysis, environmental catalysis and green catalytic processes.

What are the 5 factors that affect the rate of reaction quizlet?

5 Factors Affecting the Rate of Reaction

  • Nature of Reactants.
  • Surface Area (more = faster)
  • Temperature (higher = faster)
  • Concentration (larger = faster)
  • Catalyst (present = faster)

Which will increase the rate of a chemical reaction quizlet?

Does increasing molarity increase rate of reaction?

Increasing the concentration of reactants generally increases the rate of reaction because more of the reacting molecules or ions are present to form the reaction products. When concentrations are already high, a limit is often reached where increasing the concentration has little effect on the rate of reaction.

Which factor can decrease the rate of a chemical reaction?

temperature

Does diluting a solution increase or decrease the rate of reaction?

The more the solution of a reactant is diluted, the slower the reaction will occur.

What is rate of reaction write two factors that affect the rate of reaction?

Answer. 1)concentration of reactants. 2)temperature.

Which best explains why sawdust burns more quickly?

Which best explains why sawdust burns more quickly than a block of wood of equal mass under the same conditions? The pressure of oxygen is greater on the sawdust. More molecules in the sawdust can collide with oxygen molecules. Oxygen is more concentrated near the sawdust than the block of wood.

Which will cause an increase in the reaction rate?

Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.

Which will cause an increase in the reaction between molecules?

Which will cause an increase in the reaction rate between molecules? Molecules have strong internal bonding. Molecules collide more frequently. Electrons in the bonds remain in a meta-stable state.

Which change will cause the greatest increase in the reaction rate?

catalyst

What will happen if pressure is increased?

When there is an increase in pressure, the equilibrium will shift towards the side of the reaction with fewer moles of gas. When there is a decrease in pressure, the equilibrium will shift towards the side of the reaction with more moles of gas.

Which action would most likely increase the reaction rate for this step?

Explanation: The option that would likely increase the rate of reaction would be to use a more concentrated potassium hydroxide. The concentration of reactants is one of the factors that affect the rate of reaction. The more the concentration of the reactants, the faster the rate of reaction.

What does the equilibrium constant expression depends on?

The equilibrium-constant expression depends on the stoichiometry of the reaction. It is the coefficients and concentrations of the chemical species present in the equilibrium constant expression.

Why does equilibrium constant change with temperature?

Changing temperature Increasing the temperature decreases the value of the equilibrium constant. Where the forward reaction is endothermic, increasing the temperature increases the value of the equilibrium constant. The position of equilibrium also changes if you change the temperature.
