Question

At 1000 K, the value of $K_p$ for the following reaction is $0.05$ atm. The value of $K_c$ in terms of R would be?
$A\left(g\right)+2B\left(g\right)\rightleftharpoons 3C\left(g\right)+D\left(g\right)$

• A. $20000R$
• B. $0.02R$
• C. $5\times {10}^{-5}R$
• D. $5\times {10}^{-5}{R}^{-1}$

Answer 1

The correct option is D $5\times {10}^{-5}{R}^{-1}$

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

$\Delta n=4-3=1$

$K_P=0.05atm,T=1000K$

$K_C=\frac{K_p}{(R\times 1000}=\frac{0.05}{(R\times 1000)}=5\times {10}^{-5}{R}^{-1}$
