The curves $M$ and $N$ represent the variation of energy with reaction coordinate for the reaction in absence and presence of catalyst
Which value represents the activation energy $(E_a)$ for the backward reaction in the presence of catalyst
| Experiment |
$[A]$ (in $mol\, L^{-1})$ |
$[B]$ (in $mol\, L^{-1})$ |
Initial rate of reaction (in $mol\, L^{-1}\,min^{-1})$ |
| $I$ | $0.10$ | $0.20$ | $6.93 \times {10^{ - 3}}$ |
| $II$ | $0.10$ | $0.25$ | $6.93 \times {10^{ - 3}}$ |
| $III$ | $0.20$ | $0.30$ | $1.386 \times {10^{ - 2}}$ |
