Answer:

C. Lmol^{-1}s^{-1}

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.

Given that:- order = 2

So,

r=K[A]^2

Units of rate of reaction = M/s

Units of [A] = M

So,

M/s=K\times (M)^2

Units of K = {Ms}^{-1}

Also, M = mol/L

So, units of second rate constant = Lmol^{-1}s^{-1}

A 0.307-g sample of an unknown triprotic acid is titrated to the third equivalence point using 35.2 ml of 0.106 m naoh. calculat
Jet001 [13]
Triprotic acid is a class of Arrhenius acids that are capable of donating three protons per molecule when dissociating in aqueous solutions.  So the chemical reaction as described in the question, at the third equivalence point, can be show as: H3R + 3NaOH ⇒ Na3R + 3H2O, where R is the counter ion of the triprotic acid. Therefore, the ratio between the reacted acid and base at the third equivalence point is 1:3. 
The moles of NaOH is 0.106M*0.0352L = 0.003731 mole.  So the moles of H3R is 0.003731mole/3=0.001244mole.
The molar mass of the acid can be calculated: 0.307g/0.001244mole=247 g/mol.

Write balanced equations that describe the following reactions. (Use the lowest possible coefficients. Use the pull-down boxes t
Gnesinka [82]

Answer :  The balanced chemical reaction will be:

HBrO_4(aq)+H_2O(l)\rightarrow H_3O^+(aq)+BrO_4^-(aq)

Explanation:

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

As we know that perbromic acid is considered a strong acid that means it will completely dissociate in water.

The balanced chemical reaction will be:

HBrO_4(aq)+H_2O(l)\rightarrow H_3O^+(aq)+BrO_4^-(aq)
