Question

What is the value for ΔSºreaction for the following reaction, given the standard entropy values?
Al2O3(s) + 3H2(g) → 2Al(s) + 3H2O(g)

Answer 1

you need a table of standard entropy values, do you have one?

Answer 2

Substance Sº(J/mol*K)
Al2O3(s) 51
H2(g) 131
Al(s) 28
H2O(g) 189

Answer 3

@JFraser is that what it is?

Answer 4

that's probably it

Answer 5

the formula for finding \(\Delta S\) is:
\[\Delta S_{rxn} = \Sigma n(\Delta S_{products}) - \Sigma m(\Delta S_{reactants})\]where \(n\) and \(m\) are the coefficients of each reactant and product as it appears in this balanced equation

Answer 6

Can you walk me through it step by step? I'm not good with Chemistry at all.

Answer 7

Nevermind, I got it!
