The rate of reaction depends upon the

Half life of a first order reaction is 4 s and the initial concentration of the reactants is 0.12 M. The concentration of the reactant left after 16 s is

The half -life period of a first order chemical reaction is 6.93 minutes. The time required for the completion of 99 % of the chemical reaction will be (log 2 = 0.301)

The rate of a reaction doubles when its temperature changes from 300 K to 310 K. Activation energy of such a reaction will be : (R = 8.314 JK–1 mol–1 and log 2 = 0.301)

Consider the reaction, 2A + B → products. When concentration of B alone was doubled, the half-life did not change. When the concentration of A alone was doubled, the rate increased by two times. The unit of rate constant for this reaction is

For a first order reaction (A) → products the concentration of A changes from 0.1 M to 0.025 M in 40 minutes. The rate of reaction when the concentration of A is 0.01 M is :

The plot of concentration of the reactant vs. time for a reaction is a straight line with a negative slope. The reaction follows a

Activation energy of a chemical reaction can be determined by
