1.	When the two reactants are in the same phase, then which common phase will ensure that the products are formed at the fastest pace?(a) Solid(b) Liquid(c) Gas(d) The rate of a reaction is independent of the phase of the reactantsThe question was posed to me at a job interview.Question is taken from Chemical Kinetics topic in chapter Chemical Kinetics of Chemistry – Class 12
Answer» Right choice is (c) Gas Best explanation: When TWO reactants are in the same phase, it is better for the speed if the REACTION if they are in a gaseous phase as the particles are free to move and can collide more frequently with each other, RESULTING in a CHEMICAL reaction.
