The combustion of 1 mole of methane (CH4) in a domestic furnace requires 2 moles of O2 molecules, assuming the combustion was complete or ideal. To solve this problem, use stoichiometry of the reaction's balanced chemical equation:
CH4 + 2O2 --> CO2 + 2H2O
The ratio of CH4 to O2 in terms of moles is 1:2. So 1 mole of CH4 needs 2 moles of O2.
Divide 74 by 2-37 :)

As far as I understand, you have to plot <span>t(v) = v/k.
According to this, you have to use a form like that </span>

, in which

.
Then you can see that the vertical-intercept is zero therefore the gradient should be is <span><span>1/k.
Do hope you will find my both answer helpful and useful. Regards!</span></span>
