1.	If the value of Gibbs free energy for a reaction is 20J/mol, the reaction is ___________(a) spontaneous(b) nonspontaneous(c) may be spontaneous(d) may not be spontaneousI had been asked this question in a job interview.My enquiry is from Relationship between Equilibrium Constant K, Reaction Quotient Q and Gibbs Energy G topic in section Equilibrium of Chemistry – Class 11
Answer» The correct CHOICE is (b) nonspontaneous For explanation: Is the value of Gibbs free energy for a REACTION is 20 J/mol, that MEANS it is positive,-ΔG0/RT is NEGATIVE and that e^-ΔG0/RT is greater than 1, so the K is greater than 1 this means the reaction is nonspontaneous.
