Consider the reaction below. c2h4(g) + h2(g) --> c2h6(g) which change would likely cause the greatest increase in the rate of the reaction? a) decrease temperature and decrease pressureb) increase temperature and decrease pressurec) decrease temperature and increase pressured) increase temperature and increase pressure

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?
