Question

Calculate the change of the entropy of the reaction for the formation of ammonia from nitrogen and hydrogen gas. Supply all the missing values '?'.

N2 + H2 → NH3

Substance / S° (J/mol • K)

H2 (g) / 130.7

N2 (g) / 191.6

NH3 (s) / 192.5

molar ratio of the balanced chemical equation: ?

∑nS° (product) = ?

∆nS° (rxn) = ?

What is the entropy of the reaction: ? (Write P for positive and N for negative.
