Rate Expressions Worksheet
1) Write the following for the reaction N2 + 3 H2 ( 2 NH3 • The rate expression for the reaction • The order of the reaction in each of the reagents • The overall order of the reaction
2) The rate constant for the reaction HNO3 + NH3 ( NH4NO3 is 14.5 L / mol.sec. If the concentration of nitric acid is 0.050 M and the concentration of ammonia is 0.10 M, what will the rate of this reaction be?
3) When two compounds, A and B, are mixed together, they form compound C, by a reaction that’s not well understood. Fortunately, the following rate information was experimentally determined, as shown below:
|[A] (mol/L) |[B] (mol/L) |Rate (mol/L.sec) |
|0.050 |0.050 |4.0 x 10-3 |
|0.10 |0.050 |8.0 x 10-3 |
|0.050 |0.10 |1.6 x 10-2 |
a) Determine the rate expression for this reaction.
b) Determine the rate constant for this reaction.
Le Châtlier’s Principle
Explain how the following changes in reaction conditions will affect the position of the equilibrium below, and explain your reasoning.
A(g) + B(aq) (( C(s) ΔHrxn= -453 kJ/mol
1) The pressure of A in the reaction chamber is increased.
2) The temperature of the reaction is increased by 200 C.
3) A catalyst is added to the system.
4) As the reaction progresses, more of compound B is steadily added to the reaction chamber.
5) An inhibitor is added to the reaction chamber.
6) Argon gas is added to the reaction chamber, doubling the
