Correct option is A
The correct answer is (a)
Both I and II.
The rate law in chemistry, which describes the relationship between the rate of a reaction and the concentration of reactants, is also commonly known as the
rate equation or
rate expression. Both terms refer to the mathematical equation that represents how the rate of a chemical reaction depends on the concentrations of its reactants.
1.
Rate Equation: This term is used because the rate law is an equation that relates the rate of reaction to the concentrations of reactants raised to their respective powers, as determined experimentally.
2.
Rate Expression: This term is also used interchangeably with rate law because it expresses the rate of reaction in terms of the reactant concentrations.
Information Booster: ● The general form of the rate law is: rate = k [A]^m [B]^n, where k is the rate constant, and m and n are the reaction orders with respect to each reactant. ● The rate law is determined experimentally and cannot be derived solely from the balanced chemical equation. ● The rate law helps in understanding the kinetics of a reaction, including how changes in concentration affect the reaction rate. ● The rate constant (k) in the rate law varies with temperature and is specific to each reaction.
