Consider the given plot of enthalpy of the following reaction between A and B. A + B → C + D. Identify the incorrect statement.
Consider the given plot of enthalpy of the following reaction between A and B .
$$\mathrm{A}+\mathrm{B} \rightarrow \mathrm{C}+\mathrm{D} .
$$
Identify the incorrect statement.
Official answer
(3)
Activation enthalpy to form C is $\displaystyle 5 \mathrm{~kJ} \mathrm{~mol}^{-1}$ less than that to form D .
