Question

For independent process at 300 K. Process ∆H/k J m o l^−1 ∆S/J K^−1 A -25 -80 B -22 40 C 25 -50 D 22 20 The number of non-spontaneous process from the following is_______.

Accepted Answer

Correct answer: 2. (2) ∆G=∆Η−T∆S A : ∆G (J mol^-1) = -25 x 10^3 + 80 x 300 : -ve B : ∆G (J mol^-1) = -22 x 10^3 - 40 x 300 : -ve C : ∆G (J mol^-1) = 25 x 10^3 + 300 x 50 : +ve D : ∆G (J mol^-1) = 22 x 10^3 - 20 x 300 : +ve Processes C and D are non-spontaneous.
