Integrated Rate Equations starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Integrated Rate Equations.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A reaction follows the rate law: rate = k[A]2. If the initial concentration of A is doubled, how does the half-life change?
A reaction has a rate constant of 0.1 L mol-1 s-1. What is the order of the reaction?
A reaction is found to have a constant half-life regardless of the initial concentration. What is the order of the reaction?
Describe how you would determine the order of a reaction using integrated rate equations and experimental data.
A first-order reaction has a half-life of 10 minutes. How long will it take for the reactant to be reduced to 12.5% of its original concentration?
A reaction follows the rate law: rate = k[A]2. If the initial concentration of A is doubled, how does the half-life change?
