chemical kinetics

The role of a catalyst is to change

• gibbs energy of a reaction

• enthalpy of reaction.

• activation energy of reaction.

• reaction

In the presence of a catalyst, the heat evolved or absorbed during the reaction

• increases

• decreases

• unchanged

• none of the above

Activation energy can be represented in 2D Potential Energy Surfaces

• true

• false

How will the presence of a catalyst affect the Maxwell Boltzmann distribution curve below?

(a)  

Chemical kinetics can also be used to find out about reaction mechanisms and transition states.

• true

• false
