Question

Why in gaseous reactions moles of product is more than moles of
reacant? Explain in detail and in simple terms

Aditi Gupta · Accepted Answer

Solution:

This is not true that in gaseous reactions, moles of products are
more than moles of reactants because in some of the gaseous
reactions moles of reactants are also more than the products

For example,

N2O4 (g) → 2NO2 (g)Here, moles of product are more
But in another reaction, 2NO(g) + O2 (g) → 2NO2Here, the moles of reactant are 3 and the moles of product are 2
Hence, the given statement is not always correct it depends on whatever the reaction is going on, there is no hard and fast rule for this
