Chapter 13, Problem 17E

The initial concentrations or pressures of reactants and products are given for each of the following systems. Calculate the reaction quotient and determine the direction] in which each system will proceed to leach equilibrium.

(a) $2{\text{NH}}_3\left(g\right)\rightleftharpoons {\text{N}}_2\left(g\right)+3{\text{H}}_2\left(g\right)$	$K_c=17;\left[{\text{NH}}_3\right]=0.20M,\left[{\text{N}}_2\right]=1.00M,\left[{\text{H}}_2\right]=1.00M$
(b) $2{\text{NH}}_3\left(g\right)\rightleftharpoons {\text{N}}_2\left(g\right)+3{\text{H}}_2\left(g\right)$	$K_p=6.8\times {10}^4$ initial pressures ${\text{NH}}_3=3.0\text{atm},{\text{N}}_2=2.0\text{atm},{\text{H}}_2=1.0\text{atm}$
(c) $2{\text{SO}}_3\left(g\right)\rightleftharpoons 2{\text{SO}}_2\left(g\right)+{\text{O}}_2\left(g\right)$	$K_c=0.230;\left[{\text{SO}}_3\right]=0.00M,\left[{\text{SO}}_2\right]=1.00M,\left[{\text{O}}_2\right]=1.00M$
(d) $2{\text{SO}}_3\left(g\right)\rightleftharpoons 2{\text{SO}}_2\left(g\right)+{\text{O}}_2\left(g\right)$	$K_p=16.5$ initial pressures ${\text{SO}}_3=1.00\text{atm},{\text{SO}}_2=1.00\text{atm},{\text{O}}_2=1.00\text{atm}$
(e) $2\text{NO}\left(g\right)+{\text{CI}}_2\left(g\right)\rightleftharpoons 2\text{NOCI}\left(g\right)$	$K_c=4.6\times {10}^4;\left[\text{NO}\right]=1.00M,\left[{\text{CI}}_2\right]=1.00M,\left[\text{NOCI}\right]=0M$
(f) ${\text{N}}_2\left(g\right)+{\text{O}}_2\left(g\right)\rightleftharpoons 2\text{NO}\left(g\right)$	$K_p=0.050$ initial pressures $\text{NO}=1.00\text{atm},{\text{N}}_2={\text{O}}_2=5\text{atm}$
