CHEM 2262 Chapter : Spectral Charts
Document Summary
First law: energy can neither be created nor destroyed only converted from one form to another. Second law: when converting energy from one form to another the amount of useful energy decreases. Spontaneous reaction (-): enthalpy decreases, entropy increases (enthalpy < entropy) (exergonic) Nonspontaneous reaction (+): enthalpy increases, entropy decreases (enthalpy > entropy) (endergonic) T= 100 h= 250 (delta)g= spontaneous (-) s= 3. 0. A nonspontaneous reaction occurring at 200 k with a 150 kcal decrease in enthalpy has which of the following changes in entropy. T- 200 k h=-150 ( g) = nonspontaneous (+) ( )s=-1. 0. Speed up the rate of a reaction but are not used up during the reaction. Specific (enzymes decrease activation energy and make the reaction quicker. ) Anti-bacterial hand cleaner (tricolsan) don"t need to know. Inhibitor binds to the active site and blocks access to the active site. Inhibitor binds to a site other than the active site and alters the shape of the active site.
