In a first order reaction the concentration of the reactant decreases from 800 mol/dm³ to 50 mol/dm³ in 2 × 10⁷ sec. The rate constant of the reaction in sec^-1 is

An endothermic reaction A → B has an activation energy of 15 kcal/mole and the energy of reaction is 5 kcal/mole. The activation energy for the reaction B → A is

The rate constant of a reaction at temperature 200 K is 10 times less than the rate constant at 400 K. What is the activation energy (E_a) of the reaction?

In a second order reaction, first order in each reactant A and B, which one of the following reactant mixtures will provide the highest initial rate?

The rate law for the reaction RCl + NaOH →ROH + NaCl is given by Rate = k [RCl]. The rate of this reaction

A reaction has a rate constant of 0.5 mol^-1 dm³ min^-1. If initial concentration of the reactant is 0.2 mol dm^-3, half life of the reaction is

The rate constant of nth order has units

Consider the following statements: For a second order reaction: 2A → P

The rate of reaction of spontaneous reaction is generally very slow. This is due to the fact that..
