Chemical Kinetics
1. Write a balanced chemical equation for the reaction if magnesium, Mg, with hydrochloric acid, HCl, producing an ionic compound and hydrogen gas, H2.
a. The rate of the reaction above is given to be 8M/hr at 35 degrees Celsius. What would be the predicated rate at 25 degrees Celsius? 5 degrees Celsius?
2. Some antacids come in the form of a compressed pill, while others are in the form of loose powder. Which form gives faster relief for heartburn? Explain why using collision theory.
3. Tiny particles of coal and flour make for dangerous atmospheric conditions within mines and mills. Explain this observation using collision theory. Kinetic energy would (increase, decrease or remain unchanged). Collisions would (increase, decrease or remain unchanged). The energy of activation would (increase, decrease or remain unchanged). The number of collisions with the energy of activation would be (increase, decrease or remain unchanged).
