- AIt is the minimum amount of energy it takes to start a chemical reaction.
- BIt is the intermediate compound in a chemical reaction.
- CIt is the energy needed for an exothermic reaction.
- DIt is the energy needed for an endothermic reaction.
Explanation:
Activation Energy:- The minimum energy which must be available to a chemical system with potential reactants to result in a chemical reaction
Activation energy may also be defined as the minimum energy required to start a chemical reaction.
The activation energy of a reaction is usually denoted by Ea and given in units of kilojoules per mole (kJ/ mol) or kilocalories per mole (kcal/ mol).

Phenol $\xrightarrow{{Zn\,\,dust}}X\,\xrightarrow[{Anhyd.\,AlC{l_3}}]{{C{H_3}Cl}}\,Y\xrightarrow{{Alkaline\,\,KMn{O_4}}}\,Z$
the product $Z$ is
$Ag\left( s \right)\left| {AgBr\left( s \right)\,\left| {B{r^ - }\left( {0.01\,M} \right)} \right|\,\left| {{I^ - }\left( {0.02\,M} \right)} \right|\,AgI\left( s \right)} \right|Ag\left( s \right)$
the correct information is
[Given : $K_{sp}\,\left( {AgBr} \right) = 4 \times {10^{ - 13}}$ ,
$K_{sp}\,\left( {AgI} \right)$ $ = 8 \times {10^{ - 17}},\frac{{2.303\,RT}}{F} = 0.06\,V,\,\log \,2 = 0.3]$
