Consider the propositions below, and take into consideration that they refer to a first order unimolecular reaction.
I - the rate of reaction varies linearly with the concentration of the reagent
II - the instantaneous rate is an exponential function of time
III - the half-life of the reagent depends on its initial concentration
Which of these are correct?
Answer: (I) and (II)
I have no clue. I thought that the answer was (I) and (III).
I think that (I) is correct because V = K . [Reagents]. I have no idea why "the instantenous rate is an exponential function of time", and I swear I learnt half-life as Initial Concentration / 2^t.
Can you guys give me some hints here?
