Question

The relation between $K_p$ and $K_c$ for the following reactions.
$\left(i\right)N_2\left(g\right)+3H_2\left(g\right)\rightleftharpoons 2N{H}_3\left(g\right)$
$\left(ii\right)2H_{2}O\left(g\right)\rightleftharpoons 2H_2\left(g\right)+O_2\left(g\right)$
For these two reactions;
(i) $K_{p_1}=K_c(RT{)}^x$
(ii) $K_{p_2}=K_c(RT{)}^y$

Find the sum (x+y).

• A. $1$
• B. $-1$
• C. $2$
• D. $-1.5$

Answer 1

The correct option is B $-1$

For these two reactions $K_p$
(i) $K_p=K_c(RT{)}^{-2}$
(ii) $K_p=K_c(RT{)}^1$

On comparing we get ,
$x+y=-1$
