A hydrogen lamp emits several lines in the visible region of the spectrum. One of these lines has a wavelength of 6.56 x 10^-5 cm. What is the frequency of this radiation?

c. 75.7

i think that is the right

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

the increase of protons   hope this

we need the questions , i may then you.
