45 no me HM kaise janege ki ye equilibrium me h ?
The reaction is not in equilibrium, we are just going to find the temperate for which it is at equilibrium by putting deltaG=0 so that we can find that for what temperature the reaction is going to be spontaneous (that is delta G is going to be negative)

ohk ... thank uh mam
ye 45 me 1000 Kelvin kaise aya 100 ana chahiye
We use kilo prefix for 1000,not for 100.

solve karne ke bad me 100 ana chahiye
Manu,carefully look at the value of Delta H and Delta S which is given in the question. Its very simple and basic division.

yeeepp
Tamanna, 41 me thodi help.kijiye .
delta G = delta H- T delta S For a spontaneous reaction, delta G should be negative. Humse question mein pucha hua hai ki kin conditions mein reaction spontaneous hoga irrespective of the Temperature. It is true for both options b and d, because ek mein deltaS zero hai to T.deltaS bhi 0 ho jaega so delta G is going to be equal to delta H which is given negative in the same option. Dusre option mein delta S positive and delta H negative hai. it is this case ( -x-y) which is always going to be negative, so gibb's energy is going to be negative.

thanks Tamanna now I understand.☺☺
