Determine the rate of the reaction shown directly below if the rate constant k is 1.1 x 10^–2 M^–2 s^–1, the NO concentration is 5.0 x 10^–4 M, and the H2 concentration of 8.0 x 10^–2 M Thank you! :)

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
