Document Summary

Bonding dissociation enthalpies the h asso(cid:272)iated i(cid:374) a (cid:271)o(cid:374)d: note: breaking a bond will always need an input of energy, note: the real bde is an average of different bde of this bond in different molecules. The bde of this bond varies through different molecules: steps: create a pathway using known reactions to create the desired reaction. (cid:2175)(cid:2197)= (cid:2196)(cid:2198)(cid:2175)(cid:2198)(cid:2200)(cid:2197)(cid:2186)(cid:2203)(cid:2185)(cid:2202)(cid:2201) (cid:2197: s > 0, more disorder, s < 0, less disorder. Quasi-static processes the changes from equilibrium by infinitesimally small steps therefore allowing the macrostates to remain defined the whole way through. Reversible processes a change that can be undone without any changes in the system/ surrounding by doing the reverse of the change. Gibbs (cid:2197: g < 0, spontaneous, g > 0, not spontaneous, g = 0, in equilibrium. (cid:2163) = (cid:2174)(cid:2176)(cid:2194)(cid:2196)(cid:2167) the equation when at equilibrium.
