Question

in which of the following ways the concentration of hydrazine, $N_2{H}_4$, could be increased in an equilibrium described by the equation :
$N_2\left(g\right)+2H_2\left(g\right)\rightleftharpoons N_2{H}_4\left(g\right)\Delta H=95kJ$

• A. add $N_2$
• B. add $H_2$
• C. increase the pressure
• D. heat the reaction

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A add $N_2$
B add $H_2$
C increase the pressure
D heat the reaction

According to principle, to increase product we have to add product.
Also, as no of molecules of product are less so by increasing pressure, production increases.
And as reaction is endothermic so it will be favored by heat.
