In a first order reaction, reactant concentration 'C' varies with time 't' as

For a first order reaction, the concentration of reactant :

In a first order reaction fraction of the total concentration of the reactant varies with time 't' is equal to

Plot a graph of concentration of a reactant at time t, [ (a-x)] against time for a first order reaction .Here a = initial concentration of the reactant an x = change in concentration of the reactant at any time 1 during the reaction.

What is slope of the graph of log[A] vs t for a first order reaction, where [A] is the concentration of reactant at any time t during the reaction.
