10 L of methane was heated to 100 ° C and 8 L of hydrogen was obtained.

10 L of methane was heated to 100 ° C and 8 L of hydrogen was obtained. Determine the yield of the reaction product, assuming the conditions are normal.

The reaction equation for the decomposition of methane will be: CH4 = C + 2H2.

It turns out that 2 moles of hydrogen should be released from 1 mole of methane. Since the equimolar volume of any gases under normal conditions is also the same, then from 10 liters of CH4 at 100% output, 2 * 10 = 20 liters of H2 would be released.

Now let’s calculate the hydrogen yield:

(8/20) * 100% = 40%.
