Question

For the reaction, $H_2$ (g) + $I_2\left)\right(g)\leftrightharpoons$ 2HI(g) which of the following holds good?

• A. =
• B. <
• C.
• D. >

Answer 1

The correct option is A

=

$H_2$ (g) + $I_2\left)\right(g)\leftrightharpoons$ 2HI(g)

$K_p$ = $K_c$ ${\left(RT\right)}^{\Delta n}$

where $\Delta$n = sum of coefficients of gaseous products - sum of coefficients of gaseous reactants = (2) - (1+1) = 0

Hence$K_p$ = $K_c$. So option a)

For $N_2$(g) + 3$H_2$(g)2HI(g) $\leftrightharpoons$ $2N{H}_3$ (g)$\Delta$n = 2 - (3+1) = -2

$PC{l}_5$(g) $\leftrightharpoons$ $PC{l}_3$ (g) + $C{l}_2$ (g)$△$n = 2 - 1 = 1

$N_2$+ $O_2$ $\leftrightharpoons$ 2NO$\Delta$n = 0
