Predict the sign of DeltaS in the following processes. Give reasons for your answer : N_(2_((g)))+3H_(2_((g))) to 2NH_(3_((g)))

Answer»

Solution :`N_(2_((g)))+3H_(2_((g))) to 2NH_(3_((g)))`
In the reaction, 4 moles of GASEOUS reactants form 2 molesgaseous products `(Deltan lt 0)`. Therefore disorder decreases and HENCE entropy decreases, `DeltaS lt 0.`
