Based on this reaction, find how many moles of co can be obtained starting with 7 mol ch4?

I will solve the question assuming the reaction used as below

1 CH4 (g) + 1 H2O (g) = = > 1 CO (g) + 3 H 2 (g)

In the reaction, CH4 is the reactant and CO is the wanted product. If you look at the coefficient of the substance, for every 1 mol of CH4 react there will be 1 mol of CO produced. So, if you have 7 moles of CH4 the amount of CO produced would be: 7 moles * 1/1 = 7 moles of CO

7 moles of CO

Solution:

Methane when treated with water in the presence of catalyst (i. e. Nickle) and high temperature.

produces Carbon monoxide and Hydrogen gas as shown below,

CH₄ + H₂O → CO + 3 H₂

According to this equation,

1 mole of CH₄ produces = 1 mole of CO

So,

7 moles of CH₄ will produce = X moles of CO

Solving for X,

X = (7 mole * 1 mole) / 1 mole

X = 7 moles of CO
