An electron from a hydrogen atom jumps from energy level 3 to energy level 1 and releases a photon with wavelength 434 nm. An electron from a nearby hydrogen atom also jumps from energy level 3 to energy level 1. The wavelength released by the second hydrogen atom will be: Select one:

a.
longer than 434 nm

b.
shorter than 434 nm

c.
It is impossible to predict

d.
434 nm

false

because it does not have the potential to be entirely used up

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 :

12 is it do you think so
