Temperature effect:
Temperature is one of the factors that affect ………….. of reaction. When the temperature is decreased particles move ………… and the general frequency of collisions will ………….. In addition, particles lose ………….. So, not only frequency of all collisions decrease but the proportion of ……………. collisions decreased. This leads to a lower ………..
Words to use – no, you already did temperature last week. Use your previous week’s material and brains to find proper words.
Concentration effect:
Concentration also affects reaction ……….. When concentration is increased, there are ………. particles. Increased number of particles leads to a higher ……………. of collisions. Note that in contrast to temperature, there is no change in ………….. Because the frequency of all collisions increased, the chance of a ………………. collision also increases. This leads to a higher …………
Words to use: rate, rate, successful, more, energy, frequency
Catalyst effect:
Catalyst affects the rate by lowering ……………….. energy. Because of this, there will be more particles with ……………. more than the activation energy. Note that in contrast to temperature and concentration, there is no change in the …………….. of collisions. More particles with ………………… energy increase the proportion of ……………….. collisions. This leads to a ………… rate.
Words to use: energy, frequency, higher, sufficient, the activation, successful
