2. Consider the base-catalyzed reaction: . Use the following data of initial rate v₀ to determine (a) the rate law and (b) the corresponding rate constant, including the unit, for the reaction.

1. One mole of N₂(g) at 298 K expands adiabatically from a volume of 5.0 atm to 1.0 atm in following two conditions: (a) reversibly, and (b) against a constant external pressure of 1.0 atm. The molar heat capacity at constant volume is equal to 5R/2. Determine the values of final temperature of N₂(g), for conditions (a) and (b). R = 8.314 J = 0.082 L atm

2. The pollinator insects or other animals play the role to accelerate the evolution of angiosperms. The flowers of the earliest members might coevolve with the pollinators, as the angiosperms continued to evolve. Please describe four evolutionary trends of flowers for attracting the pollinators?
