Reaction Quotient Answers
1.	   
	Cl2 (g)	+	F2 (g)		2 ClF (g)	
I	0.400		0.200		7.3	

Q =   [ClF]2     =       (7.3)2     = 666			Q > K, therefore shifts left
       [Cl2][F2]       (0.4)(0.2)

2.	Q = 0.2  	Q > K, shifts left

3.	     
(a)
	CO (g)	+	H2O (g)		CO2 (g)	+	H2 (g)	
I	0.01		0.01		0.01		0.01	

Q =  [CO2][H2]  = (0.01)(0.01)  =  1	Q > K, shifts left
       [CO][H2O]     (0.01)(0.01)

(b)
	CO (g)	+	H2O (g)		CO2 (g)	+	H2 (g)	
I	0.01		0.01		0.01		0.01	
C	+x		+x		-x		-x	
E	0.01 +x		0.01 +x		0.01 - x		0.01 – x	

K =  [CO2][H2]  = (0.01 - x)(0.01 - x)  =  0.4
       [CO][H2O]     (0.01 + x)(0.01 + x)

	(0.01 – x)  = 0.632
               (0.01 + x)

x =  2.25 x 10-3
	[CO2]eq’m = [H2]eq’m = 7.75 x 10-3 mol /L

[CO]eq’m = [H2O}eq’m = 1.25 x 10-2 mol/L

		

4.	Q < K, shifts right
[F2]eq’m = [Br2]eq’m = 0.22 mol / L
[BrF]eq’m = 1.64 mol/L
