Answer:
Rate = k[NH4+][NO2-]
Explanation:
The rate law is the equation that relates the rate of chemical reaction with the concentration or pressure of the reactants. For the above reaction between ammonium ion and nitrite ion in a solution, the rate is dependent on the availability of reactants in the solution.
The ammonium ion is first order and the overall order is second and the rate law is hence written as,
R = k [NH4+][NO2-]
It is predicted to lie at a wavelength of 91.2 nm.
Rydberg equation is a mathematical formula that is used to predicts the wavelength of light resulting from an electron moving between energy levels of an atom. Rydbery equation is used to describe the spectral wavelengths of chemical elements. The equation is made up of different components, which include n1 and n2. The n1 of the equation has a value of 1 while the n2 runs from 2 to infinity; this makes the spectral lines to converge at point 91.2 nm.
Answer is: 5,1 mol KOH.
V (KOH) = 0,8l = 0,8 dm³.
c (KOH) = 6,4 mol/dm³.
V - volume of solution.
c - concentration of solution.
c = n÷V
n - amount of substance.
n (KOH) = c·V = 6,4 mol/dm³ · 0,8 dm³ = 5,12 mol.

The correct way to balance would be
2H2 + O2 = 2H2O
