1.	The DeltaH^(@) for CO_(2)(g), CO(g) and H_(2)O(g) are -393.5, -110.5 and -241.8 kJ mol^(-1) respectively.The standard enthalpy change (in kJ) for the reaction : CO_(2)(g) + H_(2)(g) to CO(g) + H_(2)O(g) is
Answer» 524.1 41.2 `-262.5` `-41.2` Solution :`DELTAH ^(@) = Delta_(f)H^(@)(CO)+ Delta_(f)H^(@)(H_(2)O) - Delta_(f)H^(@)(CO_(2)) - Delta_(f)H^(@)(H_(2))` = `110.5 + (-241.8) -(-393.5) -0` `= 41.2 KJ`
