Please tell me the correct answer showing some explanation(i will credit 10 points and 5 stars for the best?

Question

Which of the following could be used as the units for rate of a reaction?

1) mL/s

2) g/min

3) M/min

a)1 only

b)1 and 2 only

c)2 and 3 only

d)1,2 and 3.

Answer 1

I would tick d

all 3 show change of amount of substance (concentration) per unit of time

Answer 2

ml/s indicates flow rate..  reactions should not affect volume.

g/min can be used as for example if a solid is reacted into a gas the weight would change as solids are denser than gases..

M/min is the obvious "yes" answer as M is concentration, which changes whenever there is a reaction.

so therefore, the answer is (C)   ^^

Answer 3

I answer b because how can u read the reaction with length .mL/s means that ever single second the reaction take thus reducing the volume of substance for as certain substance would react and release as a gas. Same as the mass do.And the best answer i think is mol/min i think.

Answer 4

Reaction rates are expressed in something/time unit:

all are correct, but moles/min is more likely one you'd use as most reaction rates are computed using concentration terms (moles/liter).

examples:

1) ml of water produced / sec of some reaction

2) grams of water produced / min of some reaction

3) moles of water produced / min of some reaction

Answer 5

All are correct
