Acetic acid and water react to form hydronium cation and acetate anion, like this: HCH3CO2(aq)+H2O(l)H3O(aq)+CH3CO2(aq ) .
Imagine 250. mmol of HCH3CO2 are removed from a flask containing a mixture of HCH3CO2, H2O, H3O and CH3CO2 at equilibrium, and then answer the following questions.
What is the rate of the forward, before any CH3CO2 added in water?
A. Zero
B. Greater than zero, but less than the rate of the reverse reaction.
C. Greater than zero, and equal to the rate of the reverse reaction.
D. Greater than zero, and greater than the rate of the reverse reaction.

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
