Question

Which of the following acts as limiting reagent if 3 mole of a, 1 mole of b, 2 mole of c and 3 mole of d react according to given equation? 2a + 4b + 5c + d 4x + y + 3z?

Answer 1

find the limiting reagent by the formula which is moles divided by stoichiometric coefficient
And the compound which has lowest value of this will be limiting

Stotchiometric coeff is value behind a b c and d

Here v is limiting as you can see it has lowest value which is 1/4 = 0. 25
a has 1.5
C has 0.4
D has 0.7
