Which substance would have the greatest standard molar entropy?NO2(g)N; (g)N20NO20​

Chemistry
1 answer:
Rama09 [41]3 years ago
5 0

Answer:

Option A

Explanation:

Standard molar entropy determines the randomness of a mole of substance. Thus, the larger and complex a molecule is, the larger will be its molar entropy.  

The molar entropy of gases is higher than liquids which is turn is higher than solid.  

Here , NO2 is a gas with higher complex structure (trigonal planar) than N2 (linerar), N2O (linear) and N2O2 (linear)

Hence, NO2(g) will have greatest standard molar entropy  

Option A is correct

For cm to m, you need to divide by 100 to get m:
26cm/100= 0.26m

For hr to min, you need to multiply by 60 to get min:
4hr x 60= 240min

For km to m, you need to multiply by 1000 to get m:
3.25km x 1000= 3250m

For ft to in, you need to multiply by 12 to get in:
5ft x 12=60in

So we have:
0.26m
240min
3250m
60in

Which factor contributes the most to the rates of diffusion and effusion between two gases in a mixture?
sergejj [24]

Answer:

b)The molar mass of the particles.

Explanation:

The rate of effusion of a gas is inversely proportional to the square root of its molar mass (Graham's law), a relationship that closely approximates the rate of diffusion. As a result, light gases tend to diffuse and effuse much more rapidly than heavier gases.
