Question
Help me please ASAP
Methane and water react to form carbon monoxide and hydrogen, like this:
CH,(9)+ H,O(9) - CO(g)+ 3H,(9)
Imagine 71. mmol of CO and 213. mmol of H, are added to an empty fiask, and then answer the following questions.
Zero.
What is the rate of the reverse
reaction before any CO or Hy has
been added to the fask?
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
What is the rate of the reverse
reaction Just after the CO and Hy
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.
Zere.
Greater than zero, but less than the rate of the forward reaction.
What is the rate of the reverse
reaction at equisibrium?
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 71. mmol.
How much CO is in the flask at
equilibrium?
71. mmol.
More than 71, mmol.
