Answer #1

The answer to this question is quite simple

For any spontaneous reaction delta g is negative

And now

Delta G = Delta H - T × Delta S

= 44 - (393.15× 0.119)

= 44- 46.18

= -2. 78

So both b and d statement are correct

Which means the right answer is

D. two of these

I hope this helps. If you have any query or want more detailed explanation, feel free to ask in the comments section below.
