What happens if the conditions required by collision theory are not met?Question 5Select one:a.The reaction occurs very quickly.b.The reaction does not occur.c.The reaction explodes.d.The reaction occurs slowly.

Collision theory states that for a chemical reaction to happen the reactant particles must: Be heatedCollide with each other and have sufficient energy to reactCollide with each otherHave sufficient energy to react2What is the activation energy? Minimum amount of energy needed by particles to reactThe energy released to the surroundings during a chemical reactionTemperature required to start a chemical reactionThe energy taken away from the surroundings during a chemical reaction3Which of the following factors both increases the frequency of collisions and makes the collisions more energetic? Increasing the pressureIncreasing the concentrationIncreasing the surface areaIncreasing the temperature4How do catalysts increase the rate of a reaction?They make the collisions more energeticThey increase the activation energyThey lower the activation energyThey increase the frequency of collisions

Collision theory states that reacting substances (atoms, ions, or molecules) must collide. In addition, they must collide in the correct and with sufficient to form an activated complex.

Use ideas from the collision theory to suggest why a reaction slows down as time goes on.

Select all that applyHow are the rates of chemical reactions related to collisions between reacting particles?Multiple select question.Reacting substances must collide in the correct orientation.Reacting substances (atoms, ions, or molecules) must collide.Reacting substances must collide at slow enough speeds for energy transfer to occur.Reacting substances must collide with sufficient energy to form an activated complex.

In the previous experiment (PART A) you studied the effect of concentration on the rate of reaction. Explain your observations using the collision theory
