Question

Under which of the following sets of conditions would a chemical reaction most likely proceed at the fastest rate.
1.adding an enzyme to decrease the activation energy of the reaction.
2.adding an inhibitor to prevent enzymes from interfering with the reaction.
3. decreasing temperature to prevent products from becoming denatured
4.increasing pH to decrease the acidity of the reactants.

i think it is 2 but i am wrong a lot. help

Answer 1

A chemical reaction speeds up when an enzyme that catalyzes the reaction is added.
Enzymes usually do interfere with the reaction (unless they catalyze another reaction that interferes with it, which is not the case since it isn't mentioned)
Decreasing temperature will slow down the reaction.
Increasing pH to decrease the acidity of the reactants will not necessarily speed up the reaction.

So since we're talking about the reaction rate, adding an enzyme will most likely cause the reaction to proceed at the fastest rate.

Answer 2

Thank you vary much. ;)

Answer 3

You're welcome :)

By the way: I see I made a typo in the second sentence I see, enzymes usually do NOT interfere with the reaction.

Answer 4

Thank you did not see that.
