Question

☛ Derive an expressions for GIBBSFREE ENERGY CHANGE.

Answer 1

ANSWER.....

☛Suppose a process occurs in two process :-

Step 1:-
G1 = H1 - TS1 .............. eq.(1.)

Step 2 :-
G2 = H2 - TS2............ eq (2.)
Subtract eq.1 from eq.2
G2 - G1 = H2 - TS2 - H1 + TS1
◇ G = (H2-H1) - T (S2 - S1)

☛ ◇G = ◇H - T◇ S.

Answer 2

heya......

answer is
========

suppose the process occur in two methods

step 1
G1 = H1 - TS1 ............equation 1

step 2
G2 = H2 - TS2 .......equation 2

now sub both equations

G1 - G2 = H1 - H2 + TS1 - TS2

ΔG = ΔH + ΔTS

hope it helps ^_^
