For the reactionAB+Cat equilibrium, the concentration of A is1×10-3MB is 0.15 M and C is 0.05 M. TheΔG°for the hydrolysis of A at 300 K is-XkJ/mole. The value of X is?
Report your answer by rounding it upto nearest integer.

Answer:
5.00
Solution:

AsAB+C
K=BCA=0.15×0.051×10-3
=7.5
ΔG°=-2.303RTlog10Keq
=-2.303×8.314×10-3×300log7.5
On solvingΔG°=-4.99kJ/M
-5kJ/M
Sox=5
