Q1
What is the equilibrium constant (Kc) for the reaction 2A + B ⇌ C? (2022)
Kc = [C] / ([A]^2[B])
Kc = [A]^2[B] / [C]
Kc = [B] / ([A]^2[C])
Kc = [C] / ([B][A])
Questions & Step-by-Step Solutions
What is the equilibrium constant (Kc) for the reaction 2A + B ⇌ C? (2022)
Step 1: Identify the reaction. The reaction is 2A + B ⇌ C.
Step 2: Recognize that Kc is the equilibrium constant for this reaction.
Step 3: Understand that Kc is calculated using the concentrations of products and reactants.
Step 4: Write down the formula for Kc: Kc = [products] / [reactants].
Step 5: Identify the products and reactants in the reaction. Here, C is the product and 2A and B are the reactants.
Step 6: Write the concentrations of the products and reactants. The concentration of C is [C], the concentration of A is [A], and the concentration of B is [B].
Step 7: Apply the coefficients from the balanced equation. For 2A, we raise [A] to the power of 2, and for B, we raise [B] to the power of 1 (which is just [B]).
Step 8: Combine everything into the Kc formula: Kc = [C] / ([A]^2[B]).
