Suggest four ways in which the concentration of hydrazine (N2H4), could be increased in an equilibrium described by the following equation:                                     N2(g)  +   2H2(g)  ⇌   N2H4(g)       ΔH = 95kJ.


Expert Answer

Step 1

1. Increasing the temperature:

As it is an endothermic reaction, therefore, equilibrium constant Kc will increase with an increase in the temperature. Thus, hydrazine formation is favoured on increasing the temperature.

Step 2

2. Increasing the pressure:

The number of gaseous molecules present on the reactant side is more than on the product side. So, by increasing the pressure, hydrazine formation is favoured.

Step 3

3. Use of Catalyst:

A catalyst provides an alternate low energy pathway to a reaction and hence increase the rate of rea...
