The reactant which is entirely consumed in reaction is known as limiting reagent. In the reaction `2A+4Brarr3C+4D`, when 5 moles of A react with 6 moles of B, then
(a) which is the limiting reagent?
(b) calculate the amount of C formed?

Options

A. C, 4.5 mol
B. B, 4.5 mol
C. B, 3.5 mol
D. C, 4.0 mol

Explanation

In the reaction, `2A + 4B to 3C + 4D`
2 moles of A react with 4 moles of B
5 moles of A will react with `4/2xx5=10` moles of B
Since in the reaction only 6 moles of B are there, hence B is the limiting reagent.
Now, 4 moles of B give 3 moles of C
6 Moles of B will give `3/4xx6=4.5` mol of C
