Answer 1

Explanation:

Given the reaction between 2 gases represented by

A2 and B, to give the compound AB[g).

A2/2) + B2Q = 2ABC)

At equilibrium, the concentration

of A, = 3.0 x10-3 M

of B2 = 4.2 x 10-3 M

of AB = 2.8 x 10-3 M

If the reaction takes place in a sealed vessel at

527°C, then the value of Kc will be -

(1) 0.62

(2) 4.5

(3) 2.0✓✓✓

(4) 1.9
