Interpretation:
Standard enthalpy change for the given reaction must be calculated in which FeO is reduced to Fe by CO.
Concept Introduction:
Hess’ law states that if a process is carried out separately in single and multiple steps then in both cases same amount of heat energy will be released or absorbed provided the initial and final states are same in both the cases.
Using this law standard enthalpy change for a given reaction can be calculated.
Answer to Problem 35A
Standard enthalpy change for the given reaction must be calculated in which FeO is reduced to Fe by CO is +1 kJ.
Explanation of Solution
Multiplying equation ‘1’ with 2 and reversing it, reversing equation ‘2’ and multiplying equation ‘3’ with 3
it can be written
Now adding equation ‘4’, ‘5’ and 6’ it can be written
Now dividing equation ‘7’ with 6 it can be written
Standard enthalpy change for the given reaction is +1 kJ.
