Question

A straight line was obtained on plotting $lo{g}_{10}\frac{dx}{dt}$ vs $lo{g}_{10}(a-x{)}^n$ with an intercept on log $\left(\frac{dx}{dt}\right)$ axis equal to 0.6021. The rate constant for the reaction is $x$ $litr{e}^{n-1}mo{l}^{1-n}{t}^{-1}$. $x$ is :

• A. 2
• B. 3
• C. 5
• D. 4

Answer 1

The correct option is D 4

The intercept is equal to log k
$logk=0.6021$
$k=4$
