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

Use Boyle's Law to explain what would happen to the volume of a helium- filled balloon if it was carried underwater by a diver t
oksano4ka [1.4K]

The deeper the diver takes the helium balloon, the more it reduces in size. This is due to the pressure of the water column above pressing on the balloon. According to Boyle’s law (P= k*1/V.), as the volume of the balloon decreases, the pressure of the helium inside increases.

Consider the reaction. At equilibrium, the concentrations of the different species are as follows. [NH3] = 0.105 M [N2] = 1.1 M
Zina [86]

Hey there!:

The reaction is as follows:

N2(g)+ 3 H2(g) ⇌ 2 NH3(g)

At equilibrium, the concentrations of the different species are as follows.:

[NH3] = 0.105 M

[N2] = 1.1 M

[H2] = 1.50 M

The equilibrium constant for the reaction is given as follows:

Keq = [NH3]² / [N2] [H2]³

Keq = (0.105)² / [1.1] [1.50]³

Keq = 0.00296 or 0.0030

The equilibrium constant for the reaction at this temperature is 0.0030.


Hope that helps!
