Question

Ammonia and oxygen react to form nitrogen and water, like this: Imagine 179. mmol of N_2 and 134.25. mmol of H_2O are added to an empty flask, and then answer the following question. What is the rate of the reverse reaction before any N_2 or H_2O has been added to the flask? 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. What is the rate of the reverse reaction just after the N_2 or H_2O has been added to the flask? 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. What is the rate of the reverse reaction at equilibrium? 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. How much N_2 is in the flask at equilibrium? None. Some, but less than 179 mmol. 179 mmol. More than 179 mmol.

Explanation / Answer

1. greater than zero and equal to the rate of forward reaction

2. greater than zero and greater than rate of forward reaction

3. greater than zero and equal to the rate of forward reaction

4. less than 179mmm of N2
