No, the given statement is incorrect. The formula states that the rate of a chemical reaction is equal to the change in concentration of reactants or products per unit of time. The volume of gas produced per unit of time is related to the rate of reaction but it is not directly equal to it.
The statement you provided is not entirely correct. The volume of gas produced per unit of time is not directly equal to the reaction rate. However, there is a relationship between the two. In general, the rate at which a gas is produced in a chemical reaction is proportional to the reaction rate. This means that, within certain limits, an increase in the reaction rate will lead to a corresponding increase in the volume of gas produced per unit of time.
