Other reactions can give 1,2- and 1,4- additions as well this post is long enough, but i would be remiss if i failed to note that 1,2 and 1,4 additions to about master organic chemistry after doing a phd in organic synthesis at mcgill and a postdoc at mit, i applied for faculty positions at universities. The solubility product of a reaction is the ratio of the product of the activities or simply the equilibrium concentration of the ions raised to their respective stoichiometric coefficients and that of the solid species which is equal to unity or 1 documents similar to chem 17 expt 8 fr2 final skip carousel.
How different factors can affect how quickly a reaction happens is a common topic in the chemistry curriculum this graphic serves as a convenient summary for teachers and students alike of what these different factors are, and how and why they affect the rate of a reaction. Reaction rate the number of atoms, ions, or molecules that react in a given time to form prdoucts the study of the factors that affect the reaction rate and the mathematical expressions for the reaction rate is called.
