How many reactive moles are there? - in relation to Le Chatelier's principle

For the following equilibrium reaction (CH2)3 (g) (equilibrium symbol) CH2 =CHCH3 (g)
work out how many moles are on each side.
This is a question in relation to Le Chatelier's principle.

I understand the principle but am not sure which side has most reactive moles?
Once I know this I can then work out the effect of increasing the temperature and pressure etc.

Thank you

It is an isomerization reaction where cyclopropane is being isomerized into propene. There is only 1 molecule on each side -so no effect of P.
It is an exothermic reaction so preffered at low temp.
