Hint :To solve the given question, we should have information about mole concept, Rate of reaction and stoichiometric coefficient. Rate of reaction is the change in concentration of reactant or product per unit time.
The stoichiometric coefficient represents the number that appears before a chemical reactant or formula. Stoichiometric coefficient is also the quantitative relation between the number of moles. Stoichiometric coefficients are said to be negative for reactants and positive for products.
Complete Step By Step Answer:
Step-1 :
Here, in this question, we have given two as the stoichiometric coefficient of hydrogen. The stoichiometric coefficient represents the number that appears before a chemical reactant or formula.
Step-2 :
Stoichiometric coefficient is also the quantitative relation between the number of moles. So, in the question, the blank is filled with moles as two moles of hydrogen are represented by $ 2H_2 $ .
Additional Information:
Stoichiometry is based on the law of conservation of mass. The law of conservation of mass states that mass can neither be created nor be destroyed only transformed from reactants to products.
Note :
Stoichiometric coefficients are said to be negative for reactants and positive for products. The law of conservation of mass states that mass can neither be created nor be destroyed only transformed from reactants to products.
