1.Write the expression for and {{K}_{p}}

2.What will be the equilibrium constant value for the reverse reaction at 673 K ?

3.What is the effect of increasing temperature on the yield of N${{H}*{3}} ?
4.What is the effect of adding {{N}*{2}}(g) and {{H}*{2}}(g) on the yield of N{{H}*{3}} ?
5.What is the effect of increasing pressure on the yield of NH3?

Classify the following species into Lewis acids and Lewis bases: O{{H}^{-}},{{F}^{-}},{{H}^{+}},B{{F}*{3}} Calculate the pH of a solution in which 0.4 g of NaOH is dissolved in water to give 200 mL of solution.
6.{{H}*{2}}$0 can act both as Bronsted arid and base. Write it’s corresponding conjugate base and conjugate arid.

© As this is an exothermic reaction, on increasing

the temperature, the reaction will move in reverse direction. This results in decrease in concentration of N${{H}*{3}}
(d) On increasing the concentration of {{N}*{2}}(g) and {{H}*{2}}(g), the yield of N{{H}*{3}}$ will increase.

(e) On increasing the pressure, the reaction will

move in forward reaction in which number of moles of gas or pressure decreases.
