(a) For each of the following reactions, predict the sign ofΔH° and ΔS ° without doing any calculations. (b) Basedon your general chemical knowledge, predict which ofthese reactions will have K 7 1. (c) In each case, indicatewhether K should increase or decrease with increasingtemperature.(i) 2 Mg(s) + O2(g)⇌ 2 MgO(s) (ii) 2 KI(s) ⇌ 2 K(g) + I2(g) (iii) Na2(g) ⇌2 Na(g) (iv) 2 V2O5(s) ⇌ 4 V(s) + 5 O2(g)
