Expert Answer

Step 1

An increase in entropy results from an increase in disorder.

Entropy is an extensive property (a function of number of moles).

fullscreen
Step 2

The stoichiometric coefficient of product minus coefficient of reactant used to predicts the entropy change of the system.

fullscreen
Step 3

Number of moles on the product side is 7(3+4) and the number of moles of reactant is 6(1+5)

∆S0 is 7 - (6) = 1

Six moles of reactant gives 7 mole...
