Question

When you calculated k in the rate equation for the reaction of KMnO solution and H_2 C_2 O_4 solution you the same value under the condition of determination 1.2 and 3. What assumption did you make about the reaction of KMnO_4 solution and H_2 C_2 O_4 solution in those determinations that allowed that you to Comdex' k to be a constant? Would it be sound practice to compare the results of determinations 4-6 when calculating k? Briefly explain. Do your experimental data substantiate the rule of thumb regarding the effect on the reaction rate of a 10 degree increase in reaction temperature? Briefly explain. Consider the reaction that occurs when a CIO_2 solution and a solution containing hydroxide ions (OH^-) are mixed at 0^degree C shown in Equation 18. 2CIO_2(aq) + 2 OH^-(aq) rightarrow CIO_3^-(aq) + CIO_2^-(Aq) + H_2O(l)

Explanation / Answer

(2)

The rule of thumb says that for every 100C rise in temperature, the reaction rate almost doubles as predicted by the Arrhenius equation.

S check whether your data suggests a two fold increase in reaction rate for this temperature increase. If the data suggests the same, then the rule of thumb holds for this case.
