Standard entropy of X 2 , Y 2 and XY3 are 60, 40 and 50 JK –1 mol –1 , respectively. For the reaction, 
X 2 + 
Y 2 
XY 3 
H = – 30 kJ. To be at equilibrium the temperature will be:
Text Solution
Verified by ExpertsThe correct answer is:
B
S 0 reaction = 50 – 
(60) – 
(40) = –40 JK –1
For reaction to be at equilibrium
G = 0
H – T 
S = 0 
T = 
= 
= 750 K
