A mixture of hydrogen gas and theortical amount of air at $25^(@)$ C and a total pressure of 1atm , is exploded in a closed right vessel . If the process ossurs under adiabatic conditions then using the given data anwer the question that follow :
Given :
$C(p)(N(2))and C(p)(H(2)O)"are" 8.3 and 11.3 caldeg^(-1)mol^(-1)$ not necessarily in the same order.
$DeltaH(f)[H(2)O(g)]=-57.8kcal$
$["take air as" 80% N_(2),20%O_(2)"by volume".]$
the value of $C(p)of N(2)and H(2)O$ inthe order $N(2),H_(2)O$ will be : (in cal$deg^(-1)mol^(-1)$
A. 8.3,8.3
B. 8.3,11.3
C. 11.3,11.3
D. 11.3,8.3
