Calculate the standard enthalpy change for the following reaction at 25 °C.

H₂O(g)+C(graphite)(s) ----> H₂(g)+CO(g)

deltaH rxn=_____kJ

Expert Solution

deltaH for H2 + ½ O2 = H₂O(g) -242 KJ/ mol -----1

deltaH C + ½ O2 = CO -111 KJ/mol---------2

Now arrange the 1^st equation and add with eq 2

H2 + ½ O2 = H₂O(g) -242 KJ/ mol -----1

H₂O(g) = H2 + ½ O2 242 KJ/ mol

C + ½ O2 = CO -111 KJ/mol

H₂O(g)+C(graphite)(s) ----> H₂(g)+CO(g) +131 KJ/mol
