Consider a reaction A₂(𝑔) + B₂

Question

Consider a reaction A₂(𝑔) + B₂(𝑔) ⇌ 2 AB(𝑔), atoms of A shown in red in the diagram and atoms of B shown in blue. (b) If 𝐾_𝑐= 1, which box represents the system at 𝑄 < 𝐾_𝑐?

Accepted Answer

Step 1: Understand the concept of the reaction quotient (Q) and the equilibrium constant (Kc). The reaction quotient is a measure of the relative amounts of products and reactants present during a reaction at a particular point in time. The equilibrium constant (Kc) is the value of the reaction quotient when the reaction is at equilibrium.. Step 2: In this case, the reaction is A2(g) + B2(g) ⇌ 2 AB(g). The reaction quotient Q is given by the formula Q = [AB]^2 / ([A2][B2]), where the brackets denote the concentrations of the species.. Step 3: If Q \u003c Kc, it means that the reaction is not at equilibrium and will proceed in the forward direction to reach equilibrium. This implies that the concentrations of the reactants (A2 and B2) are higher than that of the product (AB).. Step 4: Look at the boxes in the diagram. The box that represents the system at Q \u003c Kc will have more molecules of A2 and B2 (reactants) than molecules of AB (product).. Step 5: Remember that in the diagram, atoms of A are shown in red and atoms of B are shown in blue. So, molecules of A2 will be represented by two red atoms together, molecules of B2 will be represented by two blue atoms together, and molecules of AB will be represented by one red and one blue atom together.
