Give that C_(s) +O_(2_(g))to CO_(2_((g))), Delta H^(0)=-xkJ 2CO_((g))+O_(2_((g)))to 2CO_(2_((g))), Delta H^(0)=-ykJ .

C_((s))+O_(2(g))rarr CO_(2(g))+Q is ………………….

C _((s)) + O _(2 (g)) to CO _(2(g)) ,Delta H =-393.5kJ. This equation can not represent

The enthalpy of the reaction H_(2(g)) + O_(2(g)) rarr H_2O_((g)) is DeltaH_1 and that of H_(2(g)) + O_(2(g)) rarr H_(2)O_((l)) is Delta H_2 . Then

H_(2(g)) rarr 2H_((g)) , DeltaH = 400 KJ , then DeltaS_("system") at 2000 K is
