Use the table of standard entropy values to determine δsºreaction for the following reaction:
2ch3oh(l) + 3o2(g) → 2co2(g) + 4 h2o(g)

a) +70.627 j/mol*k

b) – 70.627 j/mol*k

c) +313.766 j/mol*k

d) –313.766 j/mol*k

Standar molar entropies from a table:

CH3OH (l): 126.8 J / K*mol
O2 (g): 205.1 J/ K*mol
CO2(g): 213.7 J/K*mol
H2O(g): 188.8 J/J*mol

Now use the coefficients of the reaction and sum the product entropies less the reactant entropies:

4*188.8 + 2*213.7 - 3*205.1 - 2* 126.8 = 313.7 J/mol*K

option C) +3173.766 J/mol*K
