Consider the following reaction 2A + 3B - > 2C

If you have 4moles of A and excess amount of B, what is the maximum number of moles of C that can be made by the reaction?

4

Explanation:

Given reaction is

2A + 3B - > 2C

From the above reaction for every 2 moles of A, 2 moles of C is formed and therefore for every mole of A reacted, 1 mole of C is formed

Now in this case we have 4 moles of A and excess amount of B

So in this case the limiting reagent is A and the excess reagent is B

As in this case A is the limiting reagent so for 4 moles of A reacted, 4 moles of C is formed

But formation of 4 moles of C is just expected because it is just the maximum amount of C formed as during the reaction there can be losses as well if the reaction is not done properly
