Explanation / Answer

Delta S will be calculated as follows:

Delta n = number of moles of gaseous products - number of moles of gaseous reactants

For the first reaction; Delta n = 2-1 = 1

For the second reaction; Delta n = 2-3 = -1

For the third reaction; Delta n = 4-3 = 1

For the last reaction; Delta n = 1-2 = -1

So, the reactions that has positive delta S are as follows:

A(s) + B(g) = 2C (g)

2A (g) + B (g) = 4C (g)
