rate of reaction

Question 1

what is the collision theory?

Answer 1

a reaction will only happen if the particles collide with enough energy the amount of energy required for a practical id called the activation energy

Question 2

how do we increase the rate of reaction

Answer 2

increase the frequency of collisions
increase temp which increases energy
add a catalyst

Question 3

how do we increase the rate of reaction

Answer 3

increase the frequency of collisions

Question 4

temperature affecting the rate of reaction

Answer 4

rate of reaction increases
frequency in collisions increase

Question 5

pressure affecting rate of reaction

Answer 5

same particles in smaller volume
frequency of collisions increase

Question 6

concentration affecting rate of reaction

Answer 6

increase in number of particles
increase in frequency of collisions

Question 7

equation for mean rate of reaction

Answer 7

mean rate of reaction= mass of react/time

Question 8

you can only start a reaction if ?

Answer 8

if there are enough colliding particles for the activation energy to start the reaction
