Answer:

Plants make food by a process known as photosynthesis. As the name suggests, photo or light energy is used in this process of synthesis. Plants use three ingredients: sun light, carbon dioxide (CO2) and water (H2O) to make food (sugars). The following takes place during photosynthesis:

6CO_2 + 6H_2O + (light) -> C_6H_(12)O_6 + 6)_2

The activation energy for a reaction is changed from 184 kJ/mol to 60.5 kJ/mol at 600. K by the introduction of a catalyst. If t

Ahat [919]

Answer:

The catalyzed reaction will take 1,41 s

Explanation:

The rate constant for a reaction is:

$k = A e^{-\frac{Ea}{RT}}$

Assuming frequency factor is the same for both reactions (with and without catalyst) it is possible to obtain:

${\frac{k1}{k2}} = e^{-\frac{Ea_{2}-Ea_{1}}{RT}}$

Replacing:

${\frac{k1}{k2}} = e^{-\frac{60,5kJ/mol-184kJ/mol}{8,314472x10^{-3}kJ/molK*600k}}$

${\frac{k1}{k2}} = 5,64x10^{10}$

That means the reaction occurs 5,64x10¹⁰ faster than the uncatalyzed reaction, that is 2537 years / 5,64x10¹⁰ = 4,50x10⁻⁸ years. In seconds:

4,50x10⁻⁸ years× $\frac{365days}{1year}$ × $\frac{24hours}{1day}$ × $\frac{3600s}{1hour}$ =<em> 1,41 s</em>

I hope it helps!

What is ejected from the nucleus during alpha decay?

Aloiza [94]

Hi

Alpha decay is a type of radioactive decay.
So, when Alpha decay goes through a process called "radioactive process", two neutrons and two protons comes together and is ejected from the nucleus of a radioactive atom.

Hope this helped :)
