Which statement is true regarding the function of a catalyst in a chemical reaction? a) A catalyst increases the rate of a reaction. b) A catalyst provides an alternate mechanism for the reaction. c) A catalyst is not consumed by the reaction. d) All of the above are true.
An enzyme accelerates chemical reactions by all of the following, EXCEPT:
a) Bringing reactants close together
b) Shifting equilibrium to favor the products
c) Adding temporary charges to substrates
d) Orienting chemical bonds for best reactivity
e) Straining chemical bonds that will be broken
Here is a chemical reaction: H₂O2 -> O2 + H₂O
What is/are the reactants? What is/are the products?
H₂O2 is the product while O₂ and H₂O are reactants.
There are no products or reactants as an enzyme is needed for the reaction to
occur.
There are no products or reactants as O2 and H₂O occur in the environment.
O H₂O2 is the reactant while O₂ and H₂O are products
