Question

The rate of chemical reaction depends on the nature of reactants because:

• A. the number of bonds broken in the reactant molecules and the number of bonds formed in product molecules changes
• B. some of the reactants are solids at the room temperature
• C. some of the reactants are coloured
• D. some of rectants are liquid at room temperature

Answer 1

The correct option is A the number of bonds broken in the reactant molecules and the number of bonds formed in product molecules changes

The rate of a chemical reaction depends on the nature of reactants because the number of bonds broken in the reactant molecules and the number of bonds formed in product molecules changes.

In other words, the ease with which bonds are formed and the ease with which bonds are broken determines the rate of the chemical reaction.

Option A is correct.
