Answer #1

The rate of a chemical reaction is defined as the change in amounts (concentration) of a reactant or product in a given time interval.Typical units of rate of a chemical reaction are molL-1s-1 or Ms-1 and molL-1min-1 or M/min and also molL-1hour-1 or M/hour. Therefore the option B and C are true.

Following statements about the rate of a chemical reaction is NOT true, which are shown below---

A. It can be defined as the negative change in concentration of reactant per unit time.

D. It can be defined as the negative change in concentration of products per unit time.
