Explanation / Answer

1. Identify the change in state where S decreases.

D) gas to solid (Rondomness will decrease in solids while comparing to gas)

2. Which of the following processes has a S > 0

C) CH4(g) + H2O(g) CO(g) + 3 H2(g)

Number gas molecules are increased in product side than reactant side
