JEE Mains · Chemistry · STD 12 - 3. Chemical kinetics
The rate coefficient \((k)\) for a particular reactions is \(1.3 \times 10^{-4}\,M^{-1}\, s^{-1}\) at \(100\,^oC,\) and \(1.3 \times 10^{-3}\,M^{-1}\,s^{-1}\) at \(150\,^oC\). What is the energy of activation \((E_A)\) (in \(kJ\) ) for this reaction? ( \(R =\) molar gas constant \(= 8.314\,JK^{-1}\,mol^{-1}\) )
- A \(16\)
- B \(60\)
- C \(99\)
- D \(132\)
Answer & Solution
Correct Answer
(B) \(60\)
Step-by-step Solution
Detailed explanation
According to arrhenius equation \(\log \,\frac{{{k_2}}}{{{k_1}}}\, = \,\frac{{{E_a}}}{{2.303\,\,R}}\,\left( {\frac{1}{{{T_1}}}\, - \,\frac{1}{{{T_2}}}} \right)\)…
