The second-order rate constant for the dimerization of a protein (P) P + P → P2 is 6.2 × 10−3/M · s at 25°C. Part 1 out of 2 If
siniylev [52]

Answer:

r=1.59\times 10^{-10}\ M/s

Explanation:

According to the law of mass action:-

The rate of the reaction is directly proportional to the active concentration of the reactant which each are raised to the experimentally determined coefficients which are known as orders. The rate is determined by the slowest step in the reaction mechanics.

Order of in the mass action law is the coefficient which is raised to the active concentration of the reactants. It is experimentally determined and can be zero, positive negative or fractional.

The order of the whole reaction is the sum of the order of each reactant which is raised to its power in the rate law.

From the reaction given that:-

P+P\rightarrown P_2

The expression for the rate is:-

r=k[P]^2

Given that;- k= 6.2\times 10^{-3} /Ms

[P] = 1.6\times 10^{-4} M

Thus,

r=6.2\times \:10^{-3}\times \:\left(1.6\times \:\:10^{-4}\right)^2\ M/s=1.59\times 10^{-10}\ M/s

The four major attractive forces between particles are ionic bonds, dipole-dipole attractions, hydrogen bonds, and dispersion fo
natima [27]

Answer with Explanation:

Ionic bond:It is that type of bond which formed between negative and positive ions.

Hydrogen bonding:Hydrogen bonding formed between hydrogen and high electronegative elements.

Dispersion force:It is weakest intermolecular force.It is temporary attractive force.When electrons of two adjacent atoms occupy positions that make the atoms temporary dipoles.

NaCl: In which Na is positive ion and Cl is negative ion.

Therefore, NaCl is ionic.

HF:F is highest electronegativ elements.

HF:Hydrogen bonding

HCl: Hydrogen bonding

F_2:Dispersion

. Is it possible to have an oxygen atom with 8 protons and another oxygen atom with 9 protons? Explain.
Scorpion4ik [409]

Answer:

no

Explanation:

changing the number of protons will change the atomic number, and if the atomic number is changed, it will become a different element. if you give oxygen 9 protons, it would no longer be oxygen, it would be fluoride.
