Can someone plz explain the criteria for each? DURABOX double lined solid fibreboard will protect your goods from dust, humidity and corrosion. A reaction can be thermodynamically unstable but kinetically stable because the condition are such that the rate of the reaction is zero. A mixture of coal and oxygen are kinetically stable because the condition for combustion are not obtained until the coal is heated to its ignition temperature. If a compound requires an enzyme to be degraded => kinetically stable because w/o the enzyme, the degradation would occur extremely slow, If a compound requires heat/energy input to form but no heat/energy input to degrade => thermodynamically unstable because it degrades w/o heat/energy input. Since 1-acid is the kinetically controlled product, then K1 > K2 and therefore E2 >E1 . Mol. A more common example of the opposite (thermodynamically unstable and kinetic inert) are the numerous coordination compounds of Co(III), e.g. Kinetics deals with all things that impact the rate at which a reaction occurs. One implication of that is that reaction kinetics are partially a f KROSSTECH is proud to partner with DURABOX to bring you an enormous range of storage solutions in more than 150 sizes and combinations to suit all of your storage needs.
