Chem 104 kinetics exam Study guides, Class notes & Summaries

4 factors that contribute to/change reaction rate - 1) concentration 2)reactant phase 3)temperature 4)catalyst if their is a plot of concentration over time of the reaction A--> 2B+C.Describe what the graph would look like. - A's slope would be exponentially negative since it is a reactant. Both B and C's slope would be exponentially positive since they are both products but Bs slope/line would be 2x C's due to coefficients. Steps To determine the initial rate from a graph - 1) Fin...
