Question

The reaction kinetics for reaction are studied over several temperatures. Which of the following are affected by a change in reaction temperature?

A reaction rate

B rate constant, k

C The energy of activation

D none of the above

Which of the following will effect the value of the rate constant? Circle all that may apply

A decreasing the temperature

B adding a catalyst

C decreasing the concentration of reactants a

D none of the above

Which of the following Equilibrium would be effected by pressure changes at constant temperature? Please circle all that May apply

a CO2 + H2 <==> CO + H2O

b CO + 1/2O2 <==> CO2

c 2HG + O2 <==> 2HgO

d 2H2 + O2 <==> 2H2O

e CaCO3 <==> CaO + CO2

Explanation / Answer

1) In the study of reaction kinetics a change in reaction temperature affect the reaction rate. When the temperature is raised, the average kinetic energy of the reacting molecule increases that enhances the the number of molecule that possess energy greater than the activation energy and henece the reaction rate increases.
