Answer:
- <u> reciprocal </u>
Explanation:
The <em>equilibrium constant</em> for an <em>equilibrium reaction </em>is the ratio of the equilibrium constant for the forward reaction, Kf, to the equilibrium constant for the reverse reaction, Kr:
- For A ⇄ B
- The forward reaction is: A → B, with rate constant is Kf = K₁ and
- The reverse reaction is: B → A, with rate constant Kr = K₂
When you write the reaction in the other reaction, the forward and the reverse reaction are exchanged:
- For B ⇄ A
- The forward reaction is B → A, with rate constant Kf = K₂
- The reverse reaction is A → B, with rate constant Kr = K₁
As you see:
Thus, <em>the equilibrium-constant expression for a reaction written in one direction is the </em><em><u> reciprocal</u></em><em>___</em><em> of the one for the reaction written for the reverse direction.</em>
