Question

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

• A. $- \log_{10} [A] \,vs \,t$
• B. $- \log_{e} [A] \,vs \,t$
• C. $\log_{10} [A] \,vs \,\log t$
• D. $[A] \, vs\,t$

Answer 1

Answer: (B)

$- \log_{e} [A] \,vs \,t$

Answer 2

For a first order reaction to obtain a positive slope a, graph is plotted between $-\log _{e}[A] v s t$.
