What is the difference between reaction rate, rate law, and reaction order? 1. You need to respond to my questions and to at least four classmates substantially over three days in a manner that furthers the discussion. Some ideas for responses might be: 2. Go a step further and describe the ways in which reaction rate can be expressed, including units and or equations. 3. Give specific examples of rate law expressions and explain why the reaction order is first, second or third, with respect to each reactant(s.)
