"WebThe reaction rate measures the changes in concentrations at times, t 1 and t 2. The negative sign in the expression represents the negative change in reactant concentration because as the reaction proceeds, the reactants disappear. A negative sign in the reaction rate will make the rate of reaction a positive expression. Using the same logic, the … " - Determine the rate of the reaction
