Question

X2 : 46 molecules y2 : 38 molecules xy : 8 molecules calculate the equilibrium constant for the balanced reaction between one mole of each reagent.

Answer 1

0.037.

Step-by-step explanation:

• We have the reaction: X₂ + Y₂ ↔ 2XY.

• Then, the equilibrium constant of this reaction will be

• Kc = [products]/[reactants] = {XY]² / [X₂][Y₂]

• [X₂] = 46 molecules, [Y₂] = 38 molecules, and [XY] = 8 molecules.

• So, Kc = {XY]² / [X₂][Y₂] = {8]² / [46][38] = 0.037.
