After how many seconds will the concentration of the reactant in a first order reaction be halved if the rate constant is `1.155xx10^(-3)s^(-1)`?

What is the concentration of the reactant in a first order reaction when the rate of the reaction is 0.6 s-1 and the rate constant is 0.035?

If the concentration of the reactant of a first order reaction is 10^(-1)"mol .L"^(-1) , the reaction -rate is 3xx10^(-4)"mol.L"^(-1).s^(-1) . When the concentration is 10^(-2)"mol.L"^(-1) , what is the rate of reaction ?

A reaction is of second order with respect to a reactant. How is the rate of reaction affected if the concentration of the reactant is reduced to half ? What is the unit of rate constant of such a reaction ?

The rate constant of a first order reaction is proportional to the concentration of the reactant.

The rate of a reaction increases four-fold when the concentration of reactant is increased 16 times. If the rate of reaction is 4 xx 10^(-6) mol L^(-1) s^(-1) when the concentration of the reactant is 4 xx 10^(-4) mol L^(-1) . The rate constant of the reaction will be

The rate of a reaction increases four-fold when the concentration of reactant is increased 16 times. If the rate of reaction is 4 xx 10^(-6) mol L^(-1) s^(-1) when the concentration of the reactant is 4 xx 10^(-4) mol L^(-1) . The rate constant of the reaction will be
