5. The following standard free energy changes are given for 25 C. N2 (g) 3H2 (g) 2NH3 (g) AG 33.0 kJ 4NH3 (g) 5 o2 (g) 4NO (g) 6H20 (1) AG 1011 kJ AG +173.1kJ N2 (g) O2 (g) 2NO (g) AG +102.6kJ N2 (g) 202 (g) 2NO2 (g) AG +208.4 kJ 2N2 (g) o2 (g) 2N20 (g) Combine above equations, as necessary, to obtain AG values for the the Law) Hess' s a. N20 (g) 3 /202 (g) 2 NO2 (g) AG b. 2H2 (g) O2 (g) 2H20 (l) AG c. 2NH3 (g) 202 (g) N20 (g) 3H20 (1) AG tend to go to Gdy Which of the reactions (a, b, or c) would equilibrium completion at 25 c which would reach an and products condition with significant amounts of all reactants present?Explanation / Answer
Part D
which reaction tend to go to completion....
This is when dG < 0, so this favours products
then
from your dG values, verify which are
dG < 0, i.e. negative, those will forward products
dG = 0, this is in equilbirium
dG > 0 , i.e. positive, this will favour reactants
