Which of the following are TRUE statements regarding a spontaneous reaction at constant temperature and pressure? i) ΔSuniv < 0 ii) ΔGsys < 0 iii) ΔSsys > ΔHsys/T iv) Q > K ii, iv i, ii all i, ii, iv ii, iii

Step 1
This means that the Gibbs free energy change (ΔG) for the system must be negative (ΔGsys < 0) for the reaction to occur spontaneously at constant temperature and pressure. Therefore, statement ii is true. Show more…
