QAIPMT-2010-Ch-2023: NEET 2010 Chemistry - Class 11 AIPMT-2010-Ch-2023 Solution: Standard entropies of \(X_2\), \(Y_2\) and \(XY_3\) are 60, 40…
Standard entropies of , and are 60, 40 and 50 J K mol respectively. For the reaction , kJ, to be at equilibrium, the temperature should be
Multiple Choice Options
- A 750 K
- B 1000 K
- C 1250 K
- D 500 K
Step-by-Step Verified Solution
Given reaction is :
1 2 X 2 + 3 2 Y 2 _ XY 3
We know,
_ S o = � S p r o d u c t s o _ � S r e a c tan _ t s o
= 50 - (30 + 60) = -40 J K -1 mol -1
At equilibrium _ G o = 0
_ H o = T _ S o
_ T = _ H o _ S o = _ 30 _ 10 3 _ 40 = 750 K
