Discuss the factors that affect the rate of reaction. comment on the importance of these factors when moving from lab through to commercial scale operation. [7 marks] (b) a reactant enters a 2 dm cstr at 1 mol dm and reacts as follows: 2a → r -a = 0.05 c2 mol dm-ºs find what feed rate ) will give an outlet concentration of (dm c = 0,5 mol dm3. min"

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.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
