say we have a reaction: N2O4 <====> 2NO2 for this reaction,if initial number of moles of N2O4 is 'a' can we write t = 0 a - at equilbrium a-x...

oh i think i made a mistake concentration of ammonia in initial state is 1 M not the equilbrium concentration,sir are the rest of steps correct?

sir it is the initial concentration i suppose

qrev/T = ΔS here what does ΔS signify?does it mean change in entropy of system or surroundings? how is entropy of system,surrounding and universe related to each other and which entropy is used in gibbs free energy equation?

yes sir thank you very much

than you sir for replying then answer must be wrong,sorry for wasting your time

thank you for replying sir subtracting we get x4-x3=0 x can be 1 or 0. substituting back in the equation we get a = -2 but answer given is -1.
