For the reaction 2 H₂(g) + O₂(g) → 2 H₂O(g), which equation would be used to determine the entropy change?

Question

(2A+B)-2C

C - ( A + B)

2C - ( 2A+B)

2A + B + 2C

2C - (A+B)

Answer 1

2C - (2A + B) because assuming you look at the reaction as 2A + B => 2C and we use the sum of the products minus the sum of the reactants, then you get 2C minus the sum of 2A and B.
