Answer :
Final answer:
The correct answer is option a which is '-230.4 kJ/mol'. Calculate the enthalpy change for the reaction N2(g) + 1/2O2(g) -> N2O(g) using given enthalpies.
Explanation:
The correct answer is option a which is '-230.4 kJ/mol'. Enthalpy change calculation:
- Given enthalpy change for N2(g) with O2(g) to form 2NO(g) is 181 kJ.
- The enthalpy change for the reaction N2(g) + 1/2O2(g) -> N2O(g) can be calculated as follows:N2(g) + 1/2O2(g) -> NO(g) + 1/2O2(g) (using the given enthalpies)2NO(g) -> N2O(g) + O2(g) (given reaction)By adding these two reactions, the enthalpy change for N2(g) + 1/2O2(g) -> N2O(g) is -230.4 kJ/mol.
