Question

1.Write the equilibrium constnat epression for hte following reaction. a(s)+3B(l) ->/<- 2C(aq)+D(aq) in terms of a, b, c, and d as needed

What is the equilibrium constant Kc for this reaction?

2.For the reaction 2NH(subscript3)(g) ->/-< 3H(subscript2)(g)+N(subscript2)(g) the equilibrium concentrations were found to be NH3=.25m h2=.54M n2=.75M What is the equilibirum constant for this reaction?

3. PCl5(g)->/<-PCl3(g)+Cl2(g) Kd=.0420 The concentrations of the products at equilbrium are PCl3=.120M and Cl2=.290M. -What is the concentration of the reactatn PCL5 atequilbrium?

4.At a certain temperature the equilibrium constant Kc is equal to 53.3 H2(g)+I2(g) ->/<- 2HI(g Kc=53.3 At this temperature .300M of H2 and .30M of I2 were placed in a 1.00 L container to react. What concentration of HI is present at equilibrium?

5.Note the following 2 reactions. A+2B ->/<- 2C where Kc=2.15 2C ->/<- D where Kc=.126 -Calculate the equilibrium constant(Kc) for the reaction D ->/<-A+2B Please note that in the previous question the ->/<- means reactions occurs both ways.

Explanation / Answer

1.COncentration of and b consider it to be 1 as they are solid and liquid

Kc=[C]2[D]1/1
