Question

What is the value for ΔSºreaction for the following reaction, given the standard entropy values? Al2O3(s) + 3H2(g) → 2Al(s) + 3H2O(g) –35 J/mol*K +35 J/mol*/K +179 J/mol*K –179 J/mol*K

Answer 1

The answer is C just got it right

Answer 2

Let me help you by giving the formula as it will be more useful for you.
`delta S = Sum(n) (Delta S(products)) - Sum(m)(Delta S(reactants))`. There are m and n in formula that are coefficients of the reactants and products that are given in the equation.
