Question

1. Give reasons for your choice. 2. Give reasons for rejecting other options

6. In a chemical reaction at constant temperature,
the addition of a catalyst
A increases the value of the equilibrium
constant.
B increases the fraction of molecules with more
than a given kinetic energy.
C decreases the energy released in the
chemical reaction.
D provides an alternative reaction mechanism
with a lower activation energy.
E increases the rate at which the molecules
collide with one another.

Answer 1

A is false. Adding a catalyst increases the rate of reaction but not the equilibrium.

D is true. That's exactly what a catalyst does.

What is your take ton the others.
