Question

consider the following hypothetical reaction 2A +4B=C If 8 moles of A reacts with 12 moles of B then maximum moles of C formed will be
1)4
2) 6
3)3
4) 2​

Answer 1

Answer:

the answer of this question is 3, and b is the limiting reagent over here so.

Answer 2

The correct answer is 3 moles

Given

Hypothetical reaction;

2A + 4B = C

Amount of A = 8 moles

Amount of B = 12 moles

TO FIND

Maximum moles of C formed

SOLUTION

We can simply solve the above problem as follows,

In the reaction;

2A + 4B = C

we can observe that,

2 moles of A reacts with 4 moles of B

8 moles of A will react with (4/2) × 8 = 16 moles of B

But only 12 moles of B is given.

Therefore,

B is the limiting reagent.

Limiting reagent is that reactant in a chemical reaction that is totally consumed.

So,

4 moles of B gives 1 mole of C

1 mole of B gives = 1/4 mole of C

Moles of C 12 moles of B will give = 12/4 = 3 moles

Hence, The correct answer is 3 moles
