1.	The standard enthalpies of formation of CO_(2) gas and HCOOH_((l)) are -393.7 kJ mol^(-1) and -409.2 kJ mol^(-1) respectively. Which of the following are correct?
Answer» `C_((s)) + O_(2(G)) RARR CO_(2(g)), DELTA H = - 393.7 kJ mol^(-1)` `CO_(2(g)) + H_(2(g)) rarr HCOOh_((l)) , Delta H = - 15.5 kJ mol^(-1)` `H_(2)O_((l)) + CO_((g)) rarr HCOOH_((l)) , Delta H = - 409.2 kJ mol^(-1)` `C_((s)) + H_(2(g)) + O_(2(g)) rarr H_(2)CO_(2(l)), Delta H = - 409.2 kJ mol^(-1)` SOLUTION :`C + O_(2) rarr CO_(2), Delta H_(1) = - 393.7` `C + H_(2) + O_(2) rarr HCOOH, Delta H_(2) = - 409.2` `H_(2)CO_(2) rarr HCOOH` `Delta H = Delta H_(2) - Delta H_(1) = - 15.5KJ`
