QAIPMT-2005-Ch-2509: NEET 2005 Chemistry - Class 11 AIPMT-2005-Ch-2509 Solution: In a face-centered cubic lattice a unit cell is shared equally…
In a face-centered cubic lattice a unit cell is shared equally by how many unit cells? 2 4 6 8
Multiple Choice Options
- A T _ S < _ H and both _ H and _ S are +ve
- B T _ S > _ H and _ H is +ve and _ S are _ ve
- C T _ S > _ H and both _ H and _ S are +ve
- D T _ S = _ H and both _ H and _ S are +ve
Step-by-Step Verified Solution
_ G = _ H � T _ S
For spontaneous reaction, _ G has to be negative.
Among the given options, it is positive only when
T _ S > _ H and both _ H and _ S are +ve .
