Q: If the equilibrium constant Kc for a reaction is 10, what is the value of Kc for the reverse reaction? (2020)

Solution: For the reverse reaction, Kc is the reciprocal of the forward reaction. Therefore, Kc (reverse) = 1/Kc (forward) = 1/10 = 0.1.

Steps: 6

Step 1: Understand that Kc is a value that describes the ratio of products to reactants at equilibrium for a chemical reaction.
Step 2: Recognize that the given Kc value (10) is for the forward reaction.
Step 3: Know that for the reverse reaction, the Kc value is the reciprocal of the forward reaction's Kc value.
Step 4: Calculate the Kc for the reverse reaction by taking 1 divided by the Kc of the forward reaction: Kc (reverse) = 1 / Kc (forward).
Step 5: Substitute the value of Kc (forward) into the equation: Kc (reverse) = 1 / 10.
Step 6: Perform the calculation: Kc (reverse) = 0.1.
