# Achieving Equilibrium

APCHEM-9QXXZA

Consider a process represented by the following equation:

$$\text{Reactants} \rightleftarrows \text{Products}$$

Assume that the system initially contains only the reactants.

The four sentences below each describe something about this system.

Identify the one that is FALSE.

A

The forward reaction starts at a high rate and then slows down over time.

B

The reverse reaction starts at a rate of 0 but speeds up over time.

C

Eventually, the forward reaction has slowed enough, and the reverse reaction has sped up to the point that their rates are equal.

D

Once the forward and reverse rates have equalized, the system will contain equal quantities of reactants and products.
