Which of the following reactions have a positive delta S rxn? check all that apply
1) A(s)+2B(g) -->C(g)
2) 2A(g)+3B(g) -->4C(g)
3) 2A(g)+2B(g) -->5C(g)
4) 2A(g)+B(s) -->3C(g)
Not sure how to tell if the reaction is positive.

More gas, the greater the Entropy (disorder).No on 1,2,4. On 3, more gase is created in the product side, Entropy increases
