Need an example?

Answer 6

Here.

If C3H8+5O2>>3CO2+4H2O has 1.5 moles of C3H8 and 15 moles of O2 reacting...

then you need to make two ratios, a problem ratio, and a equation ratio

the problem ratio is the statement of (1.5 moles of C3H8 and 15 moles of O2 reacting)

so the problem ratio=1.5/15=0.10

the equation ratio is what's actually on the equation, in this case there is 1 mole of C3H8 and 5 moles of O2.

problem ratio=1/5=0.2

now the important part is...if the mole ratio in the problem is > than then the equation, then the numerator is excess, and the denominator is limiting.

if the problem ratio < equation ratio, then the denominator is excess, and the numerator is limiting.
