1.At high temperatures, nitrogen dioxide,NO2, decomposes intoNOandO2. Ify(t) is the concentration ofNO2 (in moles per liter), then at 600ºK,y(t) changes according to the reaction lawdy/dt= −.05y2 for timetin seconds.

A.Expressyin terms oftand the initial concentrationyo.

Equation of y in terms of t and initial concentration yo

Solve for constant of integration.

Solve for differential equation.

Hello, I can't seem to find the proper method to set up this problem. The chem. stuff is slightly misleading and I can't seem to come up with anything satisfying.Any help on setting this up would be appreciated!

The one below is merely an extension of the aforementioned question, when I figure out the one above it shouldn't be too difficult.

B.Assuming that the concentration ofNO2 is twice as high att= 20 seconds as it is at 100 seconds, find the exact initial concentration of theNO2. Reminder: “Exact” means no calculator numbers.

Exact initial concentration yo
