(b) 1.9
(c) 0.62
(d) 4.5

Answer 1

Explanation:

Given the reaction between 2 gases represented by A₂ and B₂ to give the compound AB(g).

$A_2(g) + B_2(g) \rightleftharpoons 2AB(g)$.

At equilibrium, the concentration

of A₂ = 3.0 × 10⁻³ M

of B₂ = 4.2 × 10⁻³ M

of AB = 2.8 × 10⁻³ M

lf the reaction takes place in a sealed vessel at 527°C, then the value of $K_c$ will be :

(a) 2.0

(b) 1.9

(c) 0.62

(d) 4.5✔️✔️✔️✔️
