Document Summary
Last minute reminders: midterm 2: naming, pick the longest chain. If oh extending functional group exists: aldehyde e. i. If includes (h c = o: ketone f. i. If includes (c = o: thermo, use kelvin!!! Not celsius: keep track of units! (esp joules and kilojoules) Then answer will be in l*atm which needs to be converted to joules. Under isothermal conditions, u does not equal zero if there is a change in potential energy. For isothermal situations, h and u are equal to 0. This is because changing the identities of the chemicals changes the internal energy b. Usually u = pe + ke; but since not chemical equation, pe is constant so u = ke. Don"t forget the negative sign in the g = -nfe equation and the k = e ^ (-g/rt) equation a. G should normally be negative in dissolution equations and k should be positive. Less restriction of translation, rotational energy, doesn"t lock molecule in place e. ii.
