Plastic Speed
which ones of these speed up a reaction in a chemical a+b=plastic scenario?
a-increase temp
b-increase amt. of solvent used for reaction
c-add a catalyst
d-decrease the grams of reactant b and keep the volume the same
answer can be more than one or all-Plz explain thank you : )
A and C.
Because:
A: True. Temperature causes a higher energy of the molecules that are reacting. Higher energy = higher collision rate. A higher collision rate is correlated to higher speed of the completion of the reaction.
B. False. a and b are solute (assumed), and an increase in the solvent will cause a lower probability of a and b coming into contact with eachother.
C. True. Catalysts speed up the reaction. The reason it speeds up is that it involved in the process of a + b to plastic, but itself is not used in the reaction, it causes the energy of activation to be lower and allow for a lower energy to reach the transition state.
D. False. With less b, lower probability of a and b coming into contact with eachother.
