AP Chemistry Flashcards: Free Energy Of Dissolution

Study Free Energy Of Dissolution in AP Chemistry with focused flashcards that help you recognize the idea, recall the key rule, and apply it in practice-style prompts.

QUESTION

Calculate △G\triangle G given △H=10 kJ/mol\triangle H = 10 \text{ kJ/mol}, T=298 KT = 298 \text{ K}, △S=50 J/mol\cdotpK\triangle S = 50 \text{ J/mol·K}.

ANSWER

△G=−4.9 kJ/mol\triangle G = -4.9 \text{ kJ/mol}. △G=10000−298(50)=10000−14900=−4900\triangle G = 10000 - 298(50) = 10000 - 14900 = -4900 J/mol.
