Post Utme Redeemers University 2019 Chemistry Objective / Multiple Choice
Question 26 POST_UTME_REDEEMERS_UNIVERSITY • 2019 • CHEMISTRY • objective

The s\tandard Gibbs free energy change (ΔG°) for a reaction is related to the s\tandard enthalpy change (ΔH°) and s\tandard entropy change (ΔS°) by the equation: ΔG° = ΔH° - TΔS°. If the s\tandard enthalpy change for a reaction is 50 kJ/mol, the s\tandard entropy change is 0.1 kJ/mol·K, and the temperature is 298 K, what is the s\tandard Gibbs free energy change for the reaction?

Answer Options

Correct Answer A. 4.8 kJ/mol
B. -4.8 kJ/mol
C. 48 kJ/mol
D. -48 kJ/mol
Correct Answer
A
Correct Option:
4.8 kJ/mol
