Question:

What is the effect on rate of reaction when reaction moves in forward direction?

Options:

It decreases as reaction moves forward.

It increases as reaction moves forward.

It first increases then decreases.

It first decreases then increases.

Correct Answer:

It decreases as reaction moves forward.

Explanation:

The rate of reaction depends on the concentration of reactant(s) according to the rate law expression (determined experimentally). Hence, the rate of reaction decreases as the reaction moves in the forward direction because the concentration of reactant(s) decreases.
