Document Summary
If entropy driven, dh > 0 (unfavourable) and entropy increases makes the process happen (ice cube melt), if enthalpy driven, ds > 0 (unfavourable) and heat change makes the process happen. Standard states: aqueous: 1m, gasses: 100kpa, biological: [h+] = 10-7 pay attention to what standard states are defined in. Formulas: entropy: s >/= q/ t = dh/t at constant p and t. 1: increased system entropy: dssys = dhfusion/ tmelting=system. If q>k, goes to reactants, if q1, dg<0 (spon/free), if k=0, dg=0, if k<0, dg>0 (non spon/no free) therefore k = edgo/rt. Amino acids: structure, properties separation based on chemical properties, role in the cell modified aa"s with other functions in the cell (histamine, serotonin, dopamine, peptide/bonds.
