Chemical Kinetics Reaction Rates! Trivia Quiz - Quiz

Chemical reacts at different rates and could be altered(either to speed or slow the reaction) by various factors. Reaction rate, the speed at which a chemical reaction proceeds. The rate of response is always positive, except in cases where the Concentration is decreasing with time.
