Hammett plot analysis
WebAlong with The Maltese Falcon, Hammett’s The Glass Key marked the beginning of a literary golden age of crime fiction. These works helped establish the form, style, and … WebThe plot of the Hammett equation is typically seen as being linear, with either a positive or negative slope correlating to the value of rho. However, nonlinearity emerges in the Hammett plot when a substituent affects the rate of reaction or changes the rate-determining step or reaction mechanism of the reaction. For the reason of the former ...
