When initial concentration of a reactant is doubled in a
reaction, its half-life period is not effected. The order of the
reaction is

The rate of a first-order reaction is 0.04mol l -1s ^-1 at 10
seconds and 0.03mol l ^-1s ^-1 at 20 seconds after initiation of the
reaction. The half-life period of the reaction is

The decomposition of phosphine (PH₃ ) on tungsten at low
pressure is a first-order reaction. It is because the

A first order reaction has a specific reaction rate of 10^-2 sec^-1 .
How much time will it take for 20g of the reactant to reduce to
5g

When initial concentration of the reactant is doubled, the halflife
period of a zero order reaction
