Question

For a given reaction
$aA+bB⟶cC+dD$
where $a,b,c,d$ are the stoichiometric coefficients of $A,B,C,D$ respectively.
Choose the correct statement(s):

• A. $\text{Equivalents of A =Equivalents of B}$
• B. $\text{Equivalents of A}=\left(\frac{b}{a}\right)\text{Equivalents of B}$
• C. $\text{Equivalents of C =Equivalents of D}$
• D. $\text{Equivalents of C}=\left(\frac{d}{c}\right)\text{Equivalents of D}$

Answer 1

Answer: (A), (C)

The correct options are
A $\text{Equivalents of A =Equivalents of B}$
C $\text{Equivalents of C =Equivalents of D}$

Law of equivalence:

In a chemical reaction, equivalents or milliequivalents of the reactants react in equal amount to give the same number of equivalents or milliequivalents of the products separately.

There is no role of stoichiometric coefficient in the equivalent concept.

So,
$\text{Equivalents of A =Equivalents of B=Equivalents of C =Equivalents of D}$
