Astudent sets up two reactions. reaction 1 uses 0.230 mol/l of reactant, and reaction 2 uses 0.570 mol/l of reactant. how many times faster is reaction 2 compared to reaction 1?

Assuming that the rate of reaction is of first order, so that the rate is only dependent on the concentration A:

rate = - k A

So to know how much faster is reaction 2 compared to reaction 1, simply take the ratio of concentrations:

0.570 / 0.230 = 2.48

So reaction 2 is about 2.48 times faster.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
