Question

9.
In a reaction 3A + BA,B2 [NCERT Pg. 20)
If 180 atoms of A and 100 molecules of B react,
then
(1) B is limiting reactant and 100 molecules of
A,B, will be formed
(2) A is limiting reactant and 60 molecules of A B2
will be formed
(3) A is limiting reactant and 180 molecules of
A3B, will be formed
(4) B is limiting reactant and 60 molecules of A, B2
will be formed​

Answer 1

Answer:

Answer: in this reaction A is limiting reactant because for a molecule of B it requires 3 molecule of A so 100 molecules of B requires 300 molecule of A but it is only 180molecules . so A is limiting reagent.

Explanation:

A is limiting reactant and 60 molecules of A B2

will be formed
