Which of the following may suggest a catalyst has been used in a reaction, given the energy diagram for the same reaction without a catalyst?

a. activation energy is 120 kj
b. activation energy is 40 kj
c. activation energy is 60 kj
d. enthalpy is 10 kj
e. enthalpy is 40 kj

dynamic equilibrium is the answer.

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.
