Assignment:
Question 1. Explain why the rate of a simple chemical reaction such as
NO(g) + 1O2(g) → NO2(g)
is likely to be most rapid at the beginning of the reaction.
Question 2. If you wish to dissolve a lump of sugar in water, give three ways you could increase the rate at which the sugar dissolves? Explain why each procedure is effective.
Question 3. What would be the effect of an increase in temperature on the rate constant of
a) the forward reaction?
b) the reverse reaction?
Question 4. For the reaction
CO + NO2 → CO2 + NO
the activation energy for the forward reaction is 135 kJ/mol of CO reacted.
a) Determine the heat of reaction.
b) From the data given, and the ΔHr for the reaction, determine the activation energy for the reverse reaction.
c) Draw and label a potential energy diagram for the reaction.
Provide complete and step by step solution for the question and show calculations and use formulas.
