What is the formula for heat of adsorbtion

Chemistry
1 answer:
gizmo_the_mogwai [7]3 years ago
8 0

Answer:

If b values are known for different temperatures, the biosorption heats can be calculated from the plot of ln b versus 1/T. Where b0 is a constant,

ΔH (kcal·mol-1) is the heat of adsorption, R is a universal gas constant (1.987 cal·mol-1·K-1) and T is the absolute temperature (k)

What is the molecule shown below?
arsen [322]

Answer:

2,3 -Dimethyl pentane

Explanation:

The given molecule is 2,3-Dimethyl pentane.

First of all select the longest chain of C-C atom. This will be the parent name.

In given structure the longest chain is straight chain that contain five carbon. Thus the parent name will pentane and there is no double or triple bond the given structure is of alkane.

Than locate the positions of functional groups attached.

In given structure there are two methyl groups are present. Give the name in such a way that functional groups will have lowest number. In given case we will start from the left.

The first methyl group will have number 2 and second will have number 3.

The name will be,

2,3-Dimethyl pentane

A chemist fills a reaction vessel with 9.47 atm nitrogen monoxide (NO) gas, 2.61 atm chlorine (C12) gas, and 8.64 atm nitrosyl c
lys-0071 [83]

Answer:

\Delta _rG=2832.2J/mol

Explanation:

Hello,

In this case, the Gibbs free energy of that reaction is computed by computing the equilibrium constant as:

K=\frac{p_{NOCl}^2}{p_{NO}^2p_{Cl_2}} =\frac{8.64^2}{9.47^2*2.61}=0.319

Hence the Gibbs free energy:

\Delta _rG=-RTlog(K)=-8.314\frac{J}{mol*K}*298.15K*ln(0.319)\\\\\Delta _rG=2832.2J/mol

Best regards.

If it takes three "breathes" to blow up a balloon to 1.2 L, and each breath supplies the balloon with 0.060 moles of exhaled air
padilas [110]
A 3.0 L balloon is 2.5 times as big as a 1.2L balloon, and 3 times .060 equals .18, so if you multiply .18 by 2.5 you get .45 moles of air i’m pretty sure

Which Carbon is the triple bound attached to in 6-ethyl-2-octyne?
soldi70 [24.7K]

Answer:

-second

Explanation:

6-ethyl-2-octyne is an unsaturated compound with a triple bond.

6-ethyl-2-octyne will have a triple bound attached to the second carbon. The suffix -yne suggests that compound carry a triple bond and the number  "2" before suffix refers to the position of triple bond that is second carbon.

Hence, the correct option is  "-second ".

(b) Draw the structure of the products when cyclopentene is reacted with:
oee [108]

Answer:

See explanation and image attached

Explanation:

When an alkene is reacted with cold, dilute and alkaline KMnO4, the product of the reaction is a 1,2-diol (vicinal diol). The products exhibit a “syn” stereochemistry with the addition of the two -OH groups to the same side of the alkene.

The reaction of cyclopentene with cold, dilute, alkaline KMnO4 is shown in the image attached.
