Question 2 of 10 Which of the following statements concerning the collision theory of reaction rates is correct? 1. The activation energy is the difference between the EAHf° (products) and EAHf° (reactants). 2. The activation energy for the forward reaction is the negative of the activation energy for the reverse reaction. 3. The pre-exponential or frequency factor in the Arrhenius equation is a measure of the fraction of reactant molecules having sufficient energy to react. 4. The activation energy of...

Question 3 Which is not an assumption in the kinetic molecular theory for gases? The collision of one gas molecule with another (or with the walls) is completely elastic. The volume occupied the gas molecules is negligible compared to the volume of the container. Gas molecules attract each other The average kinetic energy of gas molecules is proportional to the Kelvin temperature Previous

Question 33 Which statement is TRUE according to the kinetic molecular theory? The average kinetic energy of a particle is proportional to the temperature in Kelvin. The size of the particle is large compared to the volume. The collisions of particles with one another is not completely elastic. A single particle does not move in a straight line.

Question 35 (1 point) The relationship between the activation energy of the forward and reverse reactions is related by the energy difference between the reactants and products. If the reactants are higher in energy than the products, the activation energy for the forward reaction will be smaller than the activation energy for the reverse reaction and vice versa True False Question 36 (1 point) A catalyst is a substance that is not used up during a reaction. It also does...

Dr. Megehee Which statement is false concerning collision theory and reaction rates? A) In most reactions, when reactants collide they must be in B) The the proper orientation. rate of a reaction is directly proportional to the number of effective collisions Generally, reaction rates increase by a factor of 10 for each 10 degree increase in Usually, reactions having a low Ea occur faster than ones having a high Ea- Not all collisions are effective.

According to collision theory, which condition(s) must be met in order for molecules to react? The reacting molecules must collide with sufficient energy to initiate the process of breaking and forming bonds. 2. A catalyst must be in contact with the reacting molecules for a reaction to occur. The reacting molecules must collide with an orientation that can lead to rearrangement of the atoms.
