The graph above shows the progress of a chemical reaction. Based on the graph, which of the following is true?
2 answers:
Answer: b. Reaction A is not enzyme-catalyzed, while reaction B is enzyme-catalyzed
Explanation:
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products. It is the difference between the energy of activated complex and energy of reactants.
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and convert to products.
The catalyst itself does not take part in the chemical reaction and is regenerated as such at the end.

Explanation:
Hello,
Considering the ideal equation of state:
The moles are defined in terms of mass as follows:
Whereas the gas' molar mass, thus:
Now, since the density is defined as the quotient between the mass and the volume, we get:
Solving for :
Thus, the result is given by:
