6. Write the equilibrium expression for the following reactions : (6 pts . ) a.) NH 4 CO 2 NH 2 (s) iff2NH 3 (g)+CO 2 (g) b.) 4NH 3 (g)+7O 2 (g) iff4NO 2 (g)+6H 2 O(g) c .) In addition , explain how the numerical value of the equilibrium constant could be used to determine the relative amounts of product and reactant present at equilibrium for these reactions .
Equilibrium Constant is direactly proportional to product and inversly proportional to reactants with coefficient is present as a power .
Equilibrium constant is directly proportional to temperature for endothermic reaction.
Equilibrium constant is inversly proportional to temperature for exothermic reaction .
