`X_((g)) to X_((g))^(+) +e^(-), " "DeltaH=+720kJ" "mol^(-1)`
Calculate the amoung of energy required to convert 110 mg 'X' atom in gaseous state into `X^(+)` ion. (Atoic wt. for X=7 g /mol)

A

10.4 kJ

B

12.3 kJ

C

11.3 kJ

D

14.5 kJ

Text Solution

Verified by Experts

The correct Answer is:
C
moles (n) ` = (110)/(10^3 xx 7) ` . Energy = moles ` xx 720 kJ //"mole" = 11.3 kJ mol^(-1)`
