Question

Kinetics of the permanganate and Oxalate Reaction.

2. Write out the general rate law for today's reaction with the two reactants. Use x and y for the orders of reaction for each reactant, and include the rate constant. How will the reaction rate be monitored? A B CtD Ra tekLAJEO 3. If different students use different concentrations of the same reactants, should there be any difference in calculated values for the rate constant? Why or why not? 4. Suggest two ways that the rate of the reaction can be speeded up or slowed down without changing the amounts of reactants. 5. Since both reactants are corrosive and toxic, what pictograms should be on these bottles?

Answer 1

2. xA + yB $\rightarrow$ C + D

Rate of the reaction be written as:

Rate = K[C]*[D]/ [A]^x[B]^y

3. If different students use different concentrations of same reactants definitely there will be a difference in rate of the reaction as the rate of the reaction depends on the concentration of reactants.

4. Two ways to speed up a reaction is:

1) By using a catyst

2) By increasing the temperature.

Two ways to slow down the reaction is:

1) By decreasing the temperature

2) By decreasing the pressure.

Both these ways slows down the collision between molecules.

5) For toxic chemicals the pictogram present will be the one with skull and for corrosive chemical it will be the one with 2 test tubes spilling on hands.
