Step 1: First of all, draw the boxes around each formula as shown below-. Step 2: Find out the number of atoms of each element. For Example, on reactant side, 1 for Fe, 2 H, and 1 O and on product side we have, 3 for Fe, 4 for O and 2 for H. Step 3: Start to balance the equation with the compound having maximum number of atoms.
Jun 2, 2024 · A chemical reaction is a process in which substances (reactants) are transformed into different substances (products) by breaking and forming chemical bonds.
From the study of the kinetics of many simple reactions, it is observed that for a large number of reactions, the molecularity and order are the same. Some examples are given below to justify this point. Dissociation of N2O5. N 2 O 5 → N 2 O 4 + O 2. Order = 1, Molecularity = 1. Dissociation of H2O2.
