Study Notes
Rate Expressions
- The rate expression for the reaction N2 (g) + O2 (g) → 2 NO (g) is in terms of reactants and products.
Average Rate
- The average rate of the reaction between 10 seconds and 30 seconds is calculated.
Rate Law
- The rate law for the reaction A + 2 B → C is a mathematical expression that describes the relationship between reactant concentrations and reaction rate.
Half-Life
- The half-life for the first-order reaction 2 H2O2 → 2 H2O + O2 is the time taken for the concentration of the reactant to decrease by half.
Effect of Concentration on Rate
- If the concentration of CHCl3 is increased by a factor of five while the concentration of Cl2 is kept the same, the rate of the reaction will increase.
