Nature OF Reactant || Concentration OF Reactant || Introduction OF Order || Rate Constant || Rate Law

C_(o) =initial concentration of the reactant C_(t) = concentration of the reactant at time t, k=rate constant of the reaction. Then the equation applicable for a first order reaction is

[A] = reactant concentration at time 't', k = rate constant

Assertion : The rate of reaction is the rate of change of concentration of a reactant or a product. Reason : Rate of reaction remians constant during the complete reaction.

Degree OF Dissociation OF Zero and First Order || Relation between Rate Constant OF Reaction and Rate Constant OF Different Species || Second Order Reaction || Multiple Reactant Case

In a first order reaction the concentration of the reactant is reduced to one-fourth of its initial value in 50 seconds. Cacluate the rate constant the 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 ?

Assertion : Rate of reaction doubles when concentration of reactant is doubled if it is a first order reaction. Reason : Rate constant also double.

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) ?
