Post Utme Covenant University 2022 Chemistry Question 16
Practice objective / multiple choice question 16 from the 2022 Post Utme Covenant University Chemistry examination.
Calculate the s\tandard enthalpy change (ΔH°) for the reaction: 2AgNO3(s) + Mg(s) → 2Ag(s) + Mg(NO3)2(s). Given that the s\tandard enthalpy of formation (ΔHf°) for AgNO3(s) is -206.6 kJ/mol, for Mg(s) is -147.7 kJ/mol, for Ag(s) is 0 kJ/mol, and for Mg(NO3)2(s) is -591.7 kJ/mol. Assume that the reaction occurs at cons\tant pressure.
