What does the rate of a reaction indicate about the conversion of reactants?
What does the rate of a reaction indicate about the conversion of reactants?
It indicates how fast reactants are converted into products.
How is the order of a reaction determined in a rate equation?
How is the order of a reaction determined in a rate equation?
It is determined by the power to which the concentration of a reactant is raised in the rate equation.
Define a zero-order reaction and its relationship with concentration.
Define a zero-order reaction and its relationship with concentration.
A zero-order reaction is one where the rate is not affected by the concentration of the reactant.
In a first-order reaction, how does the rate correlate with the concentration of the reactant?

Study Notes
Reaction Rates
- Reaction rates show how quickly reactants turn into products
- Units are moldm⁻³s⁻¹
- Reaction order tells how much reactant concentration affects rate
- Individual order is the power to which concentration is raised in the rate equation
- Overall order is the sum of individual orders in the rate equation
- Zero-order reactions are unaffected by reactant concentration
- First-order reactions have a rate directly proportional to reactant concentration
