1)The following equation represents one method for making Ammonia

N2(g) + 3H2(g) <--> 2NH3(g) + 92kJ

Predict the effect on the equilibrium concentrations of all substances if:

1. the temperature is increased.
2. the pressure is increased.

 

2)The Ksp's of CuCl and TlCl are 1.9X10-7 and 1.8 X 10-4 respectively.Which is more soluble?

 

3)The equilibrium system shown below has a K = 8.3 X 10-2.

2A(g) + B(s) « C(s) + 3D(g)

Blank #1 Write the equilibrium law expression for the reverse reaction

             Blank #2: Calculate the value of K of the reverse reaction. 

1)N2(g) + 3H2(g) ----->2NH3(g) + 92kJ

Here Reaction is Endothermic Since enthalpy of reaction is positive

1 )The temperature is increased: Equilibrium shits to Right

[NH3]= Increases , [N2]=Decreases [3H2]=Decreases

2)The pressure is increased:When there is an increase in pressure equilibrium will shift towards the side of the reaction with fewer moles of gas Equilibrium shits to Right

[NH3]= Increases , [N2]=Decreases [3H2]=Decreases

2) Higher Ksp value the more soluble compound

TiCl with Ksp 1.8 X 10^-4 is more soluble

3.

The equilibrium system shown below has a K = 8.3 X 10^-2.

2A(g) + B(s) « C(s) + 3D(g)

Write the equilibrium law expression for the reverse reaction

The Reverse Reaction is

C(s) + 3D(g)----->2A(g) + B(s)

Kc=[A]²/[D]³ (While writing Equilibrium constant we dont consider compounds in solid or liquid state)

Calculate the value of K of the reverse reaction

K of the reverse reaction=1/K of Forward Reaction=1/8.3 X 10^-2=12.048
