Question

For the reaction c 2h₂ ---> ch₄, how many moles of hydrogen are required to produce 10 mol of methane, ch₄

Answer 1

The number of moles of hydrogen required will be 20 moles.

Stoichiometric mole ratio

First, let us look at the balanced equation of the reaction:

$C + 2H_2 --- > CH_4$

From the above equation, it is obvious that 1 mole of carbon requires 2 moles of hydrogen in order to produce a mole of methane.

In other words, the mole ratio of hydrogen to methane is 2:1. For every 1 mole of methane produced, 2 moles of hydrogen are consumed.

Now, what we want to produce is 10 moles of methane. The amount, in moles of hydrogen required, is calculated by:

                    10 moles x 2 = 20 moles.

Thus, 20 moles of hydrogen would be required to produce 10 moles of methane.
