Some questions must be answered with a cross in a box . If you change your mind about an answer, put a line through the box and then mark your new answer with a cross . 1 This question is about re... action kinetics. (a) Maxwell‑Boltzmann distributions of the molecular energies of particles in a gas are shown at two different temperatures. The activation energy for the reaction, Ea , is labelled. T1 T2 Ea T1 < T2 Energy, E Number of molecules with energy, E (i) The activation energy is the minimum energy required (1) A for a reaction to take place when reactant molecules collide B for reactant molecules to collide C for all collisions to result in a reaction D for the particles to collide with the appropriate orientation [Show More]
