Question

For a first order reaction, to obtain a positive slope, we need to plot {where [A] is the concentration of reactant A}

(a) - log10 [A] vs t

(b) - loge [A] vs t

(c) log10 [A] vs log t

(d) [A] vs t

Answer 1

Correct option: (b) - loge [A] vs t

Explanation:

For a first order reaction the positive slope is obtained when we plot - loge [A] vs t .
