In a hypothetical reaction `X rarr Y` , the activation are 15 and `9 "kJ mol"^(-1)` respectively. The potential energy of X is `10 "kJ mol"^(-1)`

Threshold energy of the reaction is 25 kJ

The potential energy of Y is 16 kJ

Heat of reaction is 6 kJ

The reaction is exothermic

Text Solution

Verified by Experts

The correct Answer is:

Activation energy `(E_(a))`
`E_(a)=E_(("activated complex"))-E_(("ground state"))`
i.e. `" "E_(a)=E_(t)-E_(R)`
Also, `DeltaH-E_(f)-E_(b)=15-9`
`DeltaH=6" kJ"//"mol (endothermic reaction)"`
