Question

A reaction is first order with respect to reactant A and second order with respect to reactant B. The rate law for the reaction is give by
(a) rate = k [A] [B]²
(b) rate = [A] [B]²
(c) rate = k [A]² [B]
(d) rate = k [A]⁰ [B]²

Answer 1

Answer:

Option a

Explanation:

According to rate law rate of a reactants is directly proportional to product of molar concentrations of reactions each raised to some power (may or not be same as stoichiometric coefficients)

Answer 2

The specific rate constant (k) is the proportionality constant relating the rate of the reaction to the concentrations of reactants. The rate law and the specific rate constant for any chemical reaction must be determined experimentally. The value of the rate constant is temperature dependent.
