I am having a heck of a time understanding these. If you could explain the steps that would be wonderful! a. If the reaction above (c) were conducted at 273K with [NH4+] = 0.34M and [NO3-] = 0.12M, what would be the value of ΔG? Would the reaction be spontaneous in the forward or reverse direction? b. Should CrCl3 be more soluble in a solution buffered at pH = 5.5 or pH = 9.5, given that it forms the complex...
