Concept explainers
Interpretation:
Whether the given reaction is complete or not needs to be determined. Also, the percent yield of the reaction needs to be calculated.
Concept introduction:
Percent yield is the measure of efficiency of the
Explanation of Solution
No, reaction is not complete as seen in figure reactants in right hand side.
From figure one can get one atom of A reacting with two atoms of B.
So,
Here, one can see that B is limiting reactant so reaction yield depends on the B,
From stoichiometry of reaction, 2 atoms of B react to produce 1 molecule of AB2
To determine theoretical yield, 8 atoms of B are given. So, it should produce the following molecules of AB2.
Theoretical yield is 4 molecules of AB2
Actual yield given in figure
That is 3 molecules of AB2
Percent yield is the efficiency of a chemical reaction. It is determined using the following relation.
