Post Utme Uniben 2025 Chemistry Question 22
Practice objective / multiple choice question 22 from the 2025 Post Utme Uniben Chemistry examination.
The s\tandard enthalpy of formation (ΔH°f) for a compound is given by the equation ΔH°f = ΔH°f(A) + ΔH°f(B) - ΔH°f(AB). If the s\tandard enthalpy of formation for compound A is -50 kJ/mol, compound B is -30 kJ/mol, and the s\tandard enthalpy of formation for the compound AB is -80 kJ/mol, calculate the s\tandard enthalpy of formation for the compound AB.
