The rate of reaction between two reactions A and B decreases by a factor of 4 if the concentration of reactant B is doubled. The order of this reaction with respect to reactant B is

The rate of a first order reaction is 1.5 $$ \times $$ 10^$$-$$2 mol L^$$-$$1 min^$$-$$1 at 0.5 M concentration of the reactant. The half-life of the reaction is

The temperature dependence of rate constant (k) of a chemical reaction is written in terms of Arrhenius equation, $$k = A \cdot {e^{ - E{}^ * /RT}}$$. Activation energy (E^{$$ * $$}) of the reaction can be calculated by plotting

If the rate of the reaction is equal to the rate constant, the order of the reaction is
