According to kinetic theory, which two factors are important for a successful reaction to occur?
A. Collisions between particles with the right orientation
B. Collisions between particles with sufficient energy
C. Collisions between particles with the right concentrations
D. Collisions between particles with sufficient mass

A and B

Explanation: orientation and energy is all that matters

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
