Solution
-
If the temperature is raised by 10% from 310.K to 341.K, the rate of the reaction will increase. This is because the rate of a reaction is directly proportional to the temperature. When the temperature increases, the kinetic energy of the molecules increases, leading to more collisions and thus a faster reaction rate.
-
If the catalyst is removed, which raises the activation energy by 10% from 50.0/kJmol to 55.0/kJmol, the rate of the reaction will decrease. This is because a catalyst lowers the activation energy needed for a reaction to occur. If the catalyst is removed and the activation energy increases, the rate of the reaction will slow down because more energy is needed for the reaction to occur.
