Homework Answers
Q.9) here reactants has 3 gaseous molecules but product only one so ∆S is negative. ∆H also negative as combustion reaction.
∆G = ∆H -T∆S so the correct answer is option (d) ∆G <0 and K>1.
Q.10) The correct answer is option (a) ∆S is positive and spontaneous at high temperature only. As ∆S positive and ∆H positive.
Q.11) The correct answer is option (b) Phosphorus
Q.12) The correct answer is option figure E.
