Using the data in the table determine the standard Gibbs free energy and equilibrium constant for...
Using the data in the table calculate ΔGo (Delta
Go) and equilibrium the constant Kp for the
following reactions ( at 298.15K and 1bar).
a. 2NO(g) +O2 (g) <----> 2
NO2(g)
b. H2(g) +
Cl2(g) <------> HCl(g)
Based on the equilibrium constant, does the equilibrium favo the
reactants or the products?
