Methane and water react to form carbon monoxide and hydrogen, like this: CH,(9)+H,0(9) - CO(g)+3H,(g) Imagine 57. mmol of CO and 171. mmol of H, are added to an empty flask, and then answer the following questions. Zero. What is the rate of the reverse reaction before any CO or H, has been added to the flask? 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, O Greater than zero, and greater than the rate of the forward reaction. O 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. O Greater than zero, and greater than the rate of the forward reaction. What is the rate of the reverse reaction just after the CO and H has been added to the flask? O 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. O Greater than zero, and greater than the rate of the forward reaction What is the rate of the reverse reaction at equilibrium? O None. O Some, but less than 57. mmol. How much CO is in the flask at equilibrium? O 57. mmol. O More than S7. mmol.
