A) ? 2
B) 2
C) ? 22
D) ? 16
Correct Answer: C
Solution :
\[C+{{O}_{2}}\to C{{O}_{2}}\]; \[\Delta H=q\] \[C+1/2{{O}_{2}}\to CO\]; \[\Delta H=-12\] ?..(i) \[CO+1/2{{O}_{2}}\to C{{O}_{2}}\]; \[\Delta H=-10\] ?..(ii) adding equation (i) and (ii) we can get \[\Delta H=-12+(-10)=-22\]You need to login to perform this action.
