Using the data in Table 1, and the fact that the total volume of the reaction mixture in each case was 100. mL, fill in the concentration columns for [I-] and [S2O82-] in Table 2. Knowing that except for zero-order reactions the rate of a chemical reaction changes over the course of the reaction, and that the average rate can be defined as the time taken for the completion of the whole experiment and is inversely proportional to the time taken (half the time means twice the rate), fill in the three columns for the average rate below. (Just take your time from Table 1 and put it under 1 ⇒ 1/time = 1/s = sec-1)

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
