Question

) In a reason A + B2 → AB2, identify the limiting reagent in the reaction mixture
containing 5 mol A and 2.5 mol B.

Answer 1

Answer:

B is limiting reagent.

Explanation:

For calculating limiting reagent, divide the give no. of moles of subsatance by its coefficient in the equation.

Here,

For A

No. Of moles = 5

Coefficient = 1

We get 5.

For B

No. Of moles = 2.5

Coefficient = 1

We get 2.5.

Whichever no. Is smaller is the limiting reagent.

Here B is smaller hence is the lining reagent.
