The reaction of hypochlorite ion with iodide ion in 1 M aqueous hydroxide solution OCT +TOr + cr
is first order in OCT and first order in I.
Complete the rate law for this reaction in the box below.
Use the form k[A]”[B]"..., where 'l' is understood for m, n ... (don't enter 1) and concentrations taken to the zero power do not
appear.
Rate =
In an experiment to determine the rate law, the rate constant was determined to be 86.4 M's-1. Using this value for the rate constant,
the rate of the reaction when [OC] = 3.16*10-3 Mand [T] = 2.43*10-3 M would be
Ms-1

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )

it is the minimum amount of material needed to sustain a fission reaction.

critical mass is the minimum amount of fissionable material that must be assembled for a sustained fission reaction to take place. although two to three neutrons are produced for every fission, not all of these neutrons are available for continuing the fission reaction. if the conditions are such that the neutrons are lost at a faster rate than they are formed by fission, the chain reaction will not be self-sustaining.   at the point where the chain reaction can become self-sustaining, this is referred to as critical mass.
