To find the concavity just graph it or use the first derivative and pick values greater than, or less than your critical points see if those values are positive or negative. IF positive, the graph will concave up, if negative - concave downwards. To find
dehydration of a secondary alcohol proceeds readily with the presence of strong acid and proceeds with E1 mechanisms. Removing product from chemical system at equilibrium shifts the equilibrium in the direction favoring the formation of the products. I
so it is because acidic and basic conditions are used...but I'm still unsure how that gives different product ratios.
thank you!
