Kinetics Partner quiz

The rate of a reaction increases as temperature__________________.

• Decreases
• Increases
• Stays the Same

Products will form faster if____________

• the particle size of the reactants are larger.
• temperature is decreased.
• concentration of the reactants are increased.
• the reaction is not stirred.

Why does a higher concentration increase the rate of reaction?

• it increases the amount of reactants

• it lowers the activation energy

• it increases the energy of particle collisions

• it increases the frequency of particle collisions

What makes an effective collision?

• When molecules collide.
• When molecules collide with the proper orientation.
• When molecules collide with proper orientation and enough kinetic energy.
• High Temperature.

Why don't all collisions between particles cause a reaction?

• the particles also need to collide with a catalyst
• not all the particles collide with enough energy
• not all the particles collide at a high enough temperature
• the particles need to collide with each other twice

Which of the following plots will show a linear relationship for a second order reaction?

• [A] vs time

• ¹/_[A] vs time

• ln[A] vs time

• [A]² vs time

The iodide ion reacts with hypochlorite ion in the following way:

OCl^- + I^- ⟶ OI^- + Cl^-.

This rapid reaction gives the rate data shown. What is the rate law?

• rate = [OCl^-]²[I^-]

• rate = [OCl^-][I^-]²

• rate = [OCl^-][I^-]

• rate = [OCl^-]

The following data were measured for the reaction

BF₃(g) + NH_3(g) ⟶ F₃BNH_3(g)

What is the rate law for the reaction?

• rate = k[NH₃]

• rate = k[BF₃]²[NH₃]

• rate = k[BF₃][NH₃]

• rate = k[BF₃][NH₃]²
