The reaction below is exothermic and has a negative entropy change. It is spontaneous under standard conditions. What can be said about its standard Gibbs free energy change, AG*rxn? (Assume the standard temperature and pressure of 298 K and 1 atm.) 2 H₂ (g) + O2 (g) → 2 H₂O (0) AG'rxn is negative. Nothing can be said about AG rxn AG'rxn is undefined. AG*rxn is positive. AG rxn is zero.

Any phd experts there??? Question 34. In the course material you have been introduced to multiple charging for electrospray spectra. Each peak in the spectrum below can be used to provide a measure of the mass of this protein, you can work out the charge associated with each peak, and measures can be averaged to find the overall mass. Use simultaneous equations to find the charge associated with each peak in the spectra below, which will allow you to calculate the average mass of each species. Include an estimate of the error associated with this measure. Graph for Intrpt. Below is samples see calculation etc
