Question
Chapter 13 Predicting relative forward and reverse rates of reaction in a dynamic equilibrium Hydrogen and chlorine react to form hydrogen chloride, like this: H₂(9)+Cl₂(g) → 2 HCl(g) Imagine 113. mmol of HCI are added to an empty flask, and then answer the following questions. What is the rate of the reverse reaction before any HCI has been added to the flask? What is the rate of the reverse reaction just after the HCI has been added to the flask? Greater than zero, but less than the rate of the forward reaction. Greater than zero, and equal to the rate of the forward reaction. Greater than zero, and greater than the rate of the forward reaction. Zero. Greater than zero, but less than the rate of the forward reaction. Greater than zero, and equal to the rate of the forward reaction. Greater than zero, and greater than the rate of the forward reaction. None. Some, but less than 113. mmol. 113. mmol. More than 113. mmol. Using Le Chatelier's Principle to predict the result of changing concentration What is the rate of the reverse reaction at equilibrium? Zero. O Greater than zero, but less than the rate of the forward reaction. O Greater than zero, and equal to the rate of the forward reaction. Greater than zero, and greater than the rate of the forward reaction. Zero. How much HCI is in the flask at equilibrium?
