Explanation / Answer

1) we know that dGo = -RTlnK

Given dGo = 37.36 kJ

37.36 x 1000= - 8.314 x 298 lnk

K = 2.82 x 10-7

Ka is 2.82 x 10-7

2) dG =dGo + RT lnQ

dGo =-Rt lnk

dGo = - 8.314 x 298 ln 1.83 x 10-5

dGo = 27.0268 kJ

dG = 27.0268 + RT ln 6.2 x 10-8 x 0.01 / 0.1

dG = -19.796 kJ

dG is 19.796 kJ

3) probabiltiy of getting the sum 2 = 1/16

probability of getting the sum 3 = 2/16

probablity of getting the sum 4 = 3/16

probablity of getting the sum 5 = 4/16

probablity of getting the sum 6 = 3/16

probablity of getting the sum 7= 2/16

probablity of getting the sum 8 = 1/16

so the entropy is high when

The sum of the dice is 5 .
