Answer #1

AGrrn = AG products - Greactants = -13.2 + 14.3 = 1.1 kJ/mol

AG = -RTin(K)

1100 = -(8.314) (277)In(K)

K = 0.6202

Products 0.6202 = Reactants B A 1.58 +2 17 -

Solving the equation we get

r= -0,32

Hence the reaction will proceed in the reverse direction as per the data.

[B] = 1.58 - 0.32 = 1.26

[A] = 1.7 + 0.32 = 2.02
