To calculate the rate of the reaction in grams of zinc per minute, we can use the following formula:Rate of reaction = Amount of reactant used / Time taken for the reaction In this case, the amount of zinc used is 0.5 grams, and the time taken for the reaction is 3 minutes.Rate of reaction = 0.5 grams / 3 minutes = 0.1667 grams/minuteThe rate of the reaction is approximately 0.167 grams of zinc per minute.
