Find a synchronous solution of the form upper a cosine upper omega tplusupper b sine upper omega t to the given forced oscillator equation using the method of insertion, collecting terms, and matching coefficients to solve for a and b.

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)
