Question

For the reaction below, determine the standard change in entropy, ΔSº (J/K). Reference relevant Sº values in Appendix G. 3H_2(g)+N_2(g) -->2NH_3(g)

science chemistry

Answer 1

Answer #1

3H2 + N2 ------------> 2NH3

S⁰ = [2S⁰_(NH3)] - [3S⁰_(H2) + S⁰_(N2)]

S⁰ = [2(192.45) ] - [3(130.684) + (191.61)]

S⁰ = [384.9] - [583.662]

S⁰ = - 198.762 J/molK
