. For the following generic reaction: a A + b B -- > c C + d DWhat is the rate of reaction (rate expression) as a function of change in concentration (e.g. Δ[A]) andchange in time (Δt)?Describing Chemical Kinetics:1. Measuring RateThe rate of a chemical reaction is determined by:A. Change of moles of reactants/products over change in timeB. Change of grams of reactants/products over change in timeC. Change in concentration over change in timeD. change in volume over change in timeWrite the rate expressions based on the definition above for:a A + b B -- > c C + d Da A -- > productsDoes the order in reactant (m, n) in the rate law have anything to do with the coefficients of the reactants?
