Question

Match the reactions of the List I with the factors in the List II.

Answer 1

$N_2\left(g\right)+3H_2\rightleftharpoons 2N{H}_3\left(g\right)$

$K_p=K_c(RT{)}^{\Delta ng}$

$\Delta ng<0,\left(RT\right)<1,K_P>K_C$

$\left(RT\right)>1,K_c>K_p$

$\therefore K_p=\frac{4[P_{N{H}_3}{]}^2}{27\times P_{N_2}\times P^3{H}_2}$ $=\frac{4}{27}$ $\frac{P^{2}N{H}_3}{P_{N_2}\times P^3{H}_2}$

$\Delta ng=(2-4)=-2$

with increase in pressure the reaction Quotient

decrease therefore reaction moves in forward direction

The reaction for which $\Delta ng<0$ and the

lowing the values of Temperature tends to $RT<0$ therefore

reaction shift in forward direction $(1,4)$ Ans

B. As same as $A(1,4)$ (Ans)

C. $N_2+O_2\rightleftharpoons 2NO$ $\Delta ng=0$

As, $\Delta ng=0,K_p=K_e$ and therefore

no change in equilibrium with rire in presser

and reaction moves forward with ocine in temp${}^r$

by relation $\left(K=A{e}^{-Ea/RT}\right)(2,3)$ Ans

D $PC{l}_3+C{l}_2\to PC{l}_5$ $\Delta ng<0$

with increase in pressure forward shift and with Oise in

temperature the value of K increase to forward shift $(1,3)$ Ans
