How would adding the catalyst nitrogen monoxide (NO) affect this reaction? 2SO2(g) + O2(g) → 2SO3(g)

A.
NO increases the rate at which SO3 molecules are formed.
B.
NO reacts with SO3 to produce more SO2 molecules.
C.
NO decreases collisions between the SO2 and O2 molecules.
D.
NO increases the concentration of the SO2 and O2 molecules.
E.
NO increases the activation energy of the SO2 and O2 molecules.

Explanation: It would be option A

The Correct Answer is A

Explanation:

The rate increases.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
