The standard enthalpies of formation of CO2 g H... - JAMB Chemistry 1993 Question
The standard enthalpies of formation of CO2(g), H2O(g) and CO(g) in kJ mol- are -394, -242 and -110 respectively. What is the standard enthalpy change for the reaction CO(g) + H2(g)O → CO2(g) + H2(g)?
A
-42 KJ mol-
B
+42 KJ mol-
C
-262 KJ mol-
D
+262 KJ mol-
correct option: a
Standard enthalpy change of a process = ∆H° process = ∆H° F reactant - DF° products
