Oxygen sensing is important in biological studies of many systems. The variation in oxygen content of sapwood trees was measured by del Hierro and coworkers [J. Experimental Biology 53 (2002): 559] by monitoring the luminescence intensity of [Ru(dpp)3] 2 immobilized in a sol-gel that coats the end of an optical fiber implanted into the tree. As the oxygen content of the tree increases, the luminescence from the ruthenium complex is quenched. The quenching of [Ru(dpp)3] 2 by O2 was measured by Bright and coworkers [Applied Spectroscopy 52 (1998): 750] and the following data were obtained:

I0/I 3.6 4.8 7.8 12.2
% O2 12 20 47 100

Construct a Stern-Volmer plot, 4 = a + TokQ(O2), using the data supplied in the table. For (Ru(dpp)3)2+, kF =1.77 * 105 s-1

What is kQ?

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
