AP Chemistry
7.3 Reaction Quotient and Equilibrium Constant
A student investigates the reversible gas-phase synthesis of hydrogen iodide at a constant temperature of \(700\text{ K}\), represented by the balanced equation below:
\[ \text{H}_2\text{(g)} + \text{I}_2\text{(g)} \rightleftharpoons 2\,\text{HI(g)} \]
Which of the following is the correct equilibrium-constant expression, \(K_c\), for this reaction?
\[ \text{H}_2\text{(g)} + \text{I}_2\text{(g)} \rightleftharpoons 2\,\text{HI(g)} \]
Which of the following is the correct equilibrium-constant expression, \(K_c\), for this reaction?
