Question

Alguém poderia me ajudar nessa questão

Answer 1

$K_{c} = \dfrac{[HCl]^{2}}{[H_{2}] \cdot [Cl_{2}]} \\\\\\ \boxed{4,8 \cdot 10^{10} = \dfrac{[HCl]^{2}}{[H_{2}] \cdot [Cl_{2}]}}$

Temos que a nova constante é:

$K_{c}' = \dfrac{[HCl]}{[H_{2}]^{\frac{1}{2}} \cdot [Cl_{2}]^{\frac{1}{2}}} \\\\\\ K_{c}' = \sqrt{\dfrac{[HCl]^{2}}{[H_{2}] \cdot [Cl_{2}]}} \\\\\\ K_{c}' = \sqrt{K_{c}} \\\\ K_{c}' = \sqrt{4,8 \cdot 10^{10}} \\\\ \boxed{\boxed{K_{c}' = \approx 2,2 \cdot 10^{5}}}$
