What will be the rate of the reaction if 5 g of magnesium is reacting completely with dilute hydrochloric acid in two minutes?
10.0 g min
7.0 g min
3.0 g min
Amount of reactant used= 5 g
Time taken for the consumption of the reactant= 2 minutes
The rate of reaction determines the speed by which a chemical reaction proceeds. It can be calculated using the formula:
Rate of reaction=Amount of reactant usedTime taken for the consumption of the reactant ...(i)
Substituting the value of the amount of reactant and the time taken for the consumption of the reactant in equation (i) we have:
Rate of reaction=52 g/min
Rate of reaction= 2.5 g/min.
