The rate of a chemical reaction can be expressed in Molarity per secon

1.	The rate of a chemical reaction can be expressed in Molarity per seconds?(a) True(b) FalseI got this question in an international level competition.The above asked question is from Concentration Gradients and Reaction Rates in Solid Catalysts in chapter Heterogenous Reactions of Bioprocess Engineering
Answer» The correct option is (a) True Explanation: There are many factors that can either slow or speed up the RATE of a chemical reaction such as TEMPERATURE, pressure, concentration, and CATALYSTS. The Rate of a Chemical Reaction is always positive. It can be confusing since the Rate of Disappearance is negative, however when you think about it, a rate should NEVER be negative since the rate is describing how fast the concentration CHANGES with time. The units for the rate is Molarity per Seconds (M/s).
