Carbonic anhydrase is a zinc-based enzyme that catalyzes the conversion of carbon dioxide to carbonic acid. In an experiment to

study its eff ect, it was found that the molar concentration of carbon dioxide in solution decreased from 220 mmol dm−3 to 56.0 mmol dm−3 in 1.22 × 104 s. What is the rate constant of the fi rst-order reaction?

Answer:

k=1.12x10^{-4}s

Explanation:

Hello,

By considering the rate law:

ln(\frac{[CO_2]}{[CO_2]_0} )=-kt\\

Solving for the time, we've got:

k=-\frac{ln (\frac{[CO_2]}{[CO_2]_0 })}{t}\\\\k=-\frac{ln(\frac{56.0mmol*dm^{-3} }{220mmol*dm^{-3} })}{1.22x10^{4}s }\\  \\k=1.12x10^{-4}s

Best regards.

The limiting reactants appeared to be _______<br><br> Because___________
Igoryamba

Answer:

The limiting reagents seemed to be those that were consumed first .

Because when this reagent is consumed, the reaction stops. The quantity of this determines the total quantity of the product formed.

Explanation:

A limiting reagent is one that is consumed in its entirety. In this way, it delimits the amount of product that can be formed.

Take the case of two substances that interact and produce a chemical reaction. If one of the substances runs out as it is consumed during the process, the reaction will stop. The reagent consumed acts as a limiting reagent, that is, it limits the possibility of the reaction proceeding, and therefore it also limits the amount of the product generated by the reaction.

Why is it more difficult to remove an
Tom [10]
In general, the further away an electron is from the nucleus, the easier it is for it to be expelled. In other words, ionization energy is a function of atomic radius; the larger the radius, the smaller the amount of energy required to remove the electron from the outer most orbital. For example, it would be far easier to take electrons away from the larger element of Ca (Calcium) than it would be from one where the electrons are held tighter to the nucleus, like Cl (Chlorine). Hope this helped a little not the exact answer though :)

When considering light moving through a diffraction grating, you should treat the light as what?
liraira [26]

Answer:

A particle

Explanation:

Modern quantum theory holds that light has both wave-like and particle-like properties. When the length scales involved are large compared to the wavelengths of light (ex., forming images with thin lenses), the

particle nature of light dominates.
