PROBLEM SET 1 Direction: Answer the following questions. 1. A scientist conducts an experiment to determine the rate of reaction between gaseous nitrogen and oxygen. If the initial concentration of nitrogen gas was 0.500M and the concentration changed to 0.450M after 0.100s, write the balanced eauation and calculate the rate of reaction. 2. If the rate of appearance of O2 in the reaction 2OK(2)3O2(2) is 0.250M/s over the first 5.50s, how much oxygen will form during this time? 3. State the three conditions necessary for a reaction to take place between reactant particles. a) b) c) 4. Discuss the term activation energy, E0
