The standard heat of formation of at 298 K for `CCl_(4)(g), H_(2)O(g), CO_(2)(g) and HCI(g)` are -25.5, -57.8, -94.1 and -22.1 kcal `mol^(-1)` respectively. Calculate `Delta_(r)H^(Theta)` for the reaction
r`CCl_(4)(g)+2H_(2)O(g) rarr CO_(2)(g)+4HCl(g)`
Hint : `Delta_(r)H^(Theta) = sum Delta_(f)H_("Products")^(Theta)- sum Delta_(f)H_("Reactants")^(Theta)`
