Answer :

the calculated value of Kc for the new equilibrium reaction is 451.79.

How do we calculate?

Stoichiometry is described as the relationship between the quantities of reactants and products before, during, and following chemical reactions.

Stoichiometry tells us what quantity of each reactant we need in order to get enough of our desired product.

[A] = 1.53 M

[B] = 1.89 M

[C] = 2.93 M

For the reaction: 4A + 2B ↔ 8C

The balanced equation gives us the stoichiometric ratios:

[tex][A]^4 [B]^2 / [C]^8 = Kc[/tex]

Kc = ([C]^8) / ([A]^4 * [B]^2)

= [tex](2.93 M)^8 / (1.53 M)^4 * (1.89 M)^2[/tex]

= 3787.58 / 8.39

Kc = 451.79
