Assessing the Effect of Temperature on Equilibrium You are studying the various components of the venom of a poisonous lizard. One of the venom components is a protein that appears to be temperature sensitive. When heated, it denatures and is no longer toxic. The process can be described by the following simple equation:

There is only enough protein from this venom to carry out two equilibrium measurements. At 298 K, you find that 98% of the protein is in its to.\ic form. However, when you raise the temperature to 320 �.. you find that only 10% of the protein is in its toxic form.

1. Calculate the equilibrium constants for the T to N conversion at these two temperatures.
2. Use the data to determine the $\Delta H^{\circ },\Delta S^{\circ }$, and $\Delta G^{\circ }$ for this process.
