If the rate of a reaction is directly proportional to the concentration of one reactant raised to the power of 3, what is the order of the reaction? (2023)
Step 1: Understand what 'order of the reaction' means. It refers to how the rate of a reaction depends on the concentration of the reactants.
Step 2: Identify the given information. The question states that the rate of the reaction is directly proportional to the concentration of one reactant raised to the power of 3.
Step 3: Recognize that if the concentration of a reactant is raised to a power, that power indicates the order of the reaction with respect to that reactant.
Step 4: Since the concentration is raised to the power of 3, this means the reaction is third order.
Step 5: Conclude that the overall order of the reaction is 3.
Reaction Order – The order of a reaction indicates how the rate is affected by the concentration of reactants, with the exponent representing the order.
