1.	Consider the reactions `:` `C_((s))+2H_(2(g)) rarr CH_(4(g)), DeltaH=-X kcal` `C_((g))+4H_((g)) rarr CH_(4(g)),DeltaH-X_(1)kcal` `CH_(4(g))rarr CH_(3(g))+H_((g)), DeltaH=+Ykcal` The average bond energy of `C-H` bond is `:`A. `(X)/(4)` K cal. `mol^(-1)`B. Y K cal. `mol^(-1s)`C. `(X_(1))/(4)` K cal. `mol^(-1)`D. `X_(1)` K cal. `mol^(-1)`
Answer» Correct Answer - C `CH_(4(g))rarr C_((g))+4H_((g)) , Delta H= + x_(1) KCal` `therefore` B.E. of C-H bond `=(x_(1))/(4) KCal mol^(-1)`
