1.	For a reaction, Kc = 3.81 × 10^–3 and ΔG0 = 13.8 kJ/mol. Then what is the value of R?(a) -8.314J mol^–1K^–1(b) 8.314J mol^–1K^–1(c) cannot say as the temperature is not given(d) -8.314J mol^–1I had been asked this question in a national level competition.The question is from Relationship between Equilibrium Constant K, Reaction Quotient Q and Gibbs Energy G topic in division Equilibrium of Chemistry – Class 11
Answer» Correct choice is (b) 8.314J mol^–1K^–1 Easiest EXPLANATION: THOUGH the TEMPERATURE is not given, UNIVERSAL gas CONSTANT value always remains the same, whatever may be the other values. So the universal gas constant is given by a constant value that is -8.314J mol^–1K^–1.
