Print calculator Periodic Table Question 1 of 2 Map Ab Sapling Learning this question was written by John Pollard at University of Arizona Go to http://www.cbc and open the simulation. Play around with the simulation (meaning, try working all the controls and observe what happens). Now, which of the following statements are true (more than 1 can be true)? The reaction is faster when the activation energy is set to a higher value. The reaction is faster when more reactants are present. The reaction is faster when the temperature is lower. The reaction is faster when the volume is smaller.Explanation / Answer
a) False, The reaction is faster when activation energy is set to LOWER values ( since it is the enrgy required to start reaction mechanism)
b)
TRUE, When more reactants is present, the reaction goes faster
c)
Increasing T increase the rate, this is FALSE
d)
when Volumme is lower, they collide faster, therefore the reaction is faster, this is TRUE
