During a reaction, the concentration of a reactant is measured as a function of the reaction time, . All other reactants are in large excess. Which graph could be plotted to check whether the reaction is of the first order with respect to ?

The concentration of a reactant A was monitored during the course of a reaction. The data were plotted on a graph of against time. If the reaction is first order with respect to A, what is the initial concentration of A in terms of the gradient of the plot and the -intercept ?
