JEE Mains · Chemistry · STD 12 - 3. Chemical kinetics
If a reaction follows the Arrhenius equation, the plot \(\ln k\) vs \(1/(RT)\) gives straight line with a gradient \((-y)\) \(unit\). The energy required to activate the reactant is
- A \(y/R\,\)unit
- B \(y\,\)unit
- C \(yR\,\)unit
- D \(-y\,\)unit
Answer & Solution
Correct Answer
(B) \(y\,\)unit
Step-by-step Solution
Detailed explanation
\(\ln \,k = - \frac{{{E_a}}}{{RT}} + \ln \,A\) \(\therefore \) Slope \(= - E_a = -y\)
