Given that C_((g))+O_(2(g)) to CO_(2(g)) DeltaH^@=-a kJ , 2 CO_((g))+

1.	Given that C_((g))+O_(2(g)) to CO_(2(g)) DeltaH^@=-a kJ , 2 CO_((g))+ O_(2(g)) to 2CO_(2(g)) 'DeltaH^@=-b kJ , Calculate the DeltaH^@ for the reaction C_((g)) +1//2O_(2(g)) to CO_((g))
Answer» `(b+2a)/(2)` `2a-b` `(2a-b)/(2)` `(b-2a)/(2)` Solution :`DeltaH^(@)` is equal to SUMMATION `DeltaH_("Products")- " summation "DeltaH_("REACTANTS")`
