A reaction proceeds by first order, 75% of this reaction was completed in 32 min. The time required for 50% completion is

For a reaction, the rate constant is 2.34 s^-1. The half-life period for the reaction is

In a chemical reaction, two reactants take part. The rate of reaction is directly proportional to the concentration of one of them and inversely proportional to the concentration of the other. The order of reaction is

A reaction involving two different reactants can never be

In the first order reaction, the concentration of the reactants is reduced to 25% in one hour. The half-life period of the reaction is

For a reaction, X (g) → Y (g) + Z(g) the half-life period is 10 min. In what period of time would the concentration of X be reduced to 10% of original concentration ?

Chemical reactions with very high E_a values are generally

With increase in temperature, rate of reaction

Which increases on increase of temperature ?

The minimum energy required for the reacting molecules to undergo reaction is
