Question

In the reaction 4A + 2B + 3C - A4 B2C3, what will be the number of moles of product formed when we started with 1mole A, .6 mole B and .72 mole C

Answer 1

Answer:

The number of moles formed of product will be 0.14 moles.

Explanation:

$4A + 2B + 3C \rightarrow A_4B_2C_3$

$A + \frac{1}{2}B + \frac{3}{4}C \rightarrow \frac{1}{4} A_4B_2C_3$

$A + 0.5B + 7.5C \rightarrow 0.25A_4B_2C_3$

When we started with 1 mole A, 0.6 mole B and 0.72 mole C.

According to reaction 4 moles of A reacts with 2 moles B

Then 1 mole of A will give:

$\frac{2}{4}\times 1 mol=0.5 mol$ of B

According to reaction 4 moles of A reacts with 3 moles C

Then 1 mole of A will give:

$\frac{3}{4}\times 1 mol=0.75 mol$ of C

From this we can say that C is in limited amount, So moles of product will depend upon the moles of C.

According to reaction 3 moles of C gives 1 mole $A_4B_2C_3$

Then 0.72 mole of C will give:

$\frac{1}{3}\times 0.72 mol=0.14 moles$ of $A_4B_2C_3$

The number of moles formed of product will be 0.14 moles.
