A sealed isothermal container initially contains 4 moles of methanol gas, CH3OH. The following reversible reaction occurs: CH3OH (g) D 2 H2 (g) +CO (g) At equilibrium, there were 3 moles of CH3OH in the container. What is the total number of moles of gas present in the container at equilibrium?

The total number of moles of gas present in the container at equilibrium are 6 moles

Explanation:

We are given:

Initial moles of methanol = 4 moles

Equilibrium moles of methanol = 3 moles

The given chemical equation follows:

Initial:                     4

At eqllm:               4-x                2x          x

Evaluating the value of 'x':

So, equilibrium moles of hydrogen gas = 2x = 2(1) = 2 moles

Equilibrium moles of carbon monoxide gas = x = 1 mole

Total number of moles of gas =

Hence, the total number of moles of gas present in the container at equilibrium are 6 moles
