Consider the dissociation of a weak acid HA(Ka​=5.0×10−3) in water: HA(aq)⇄H+(aq)+A−(aq) Calculate ΔG∘ for this process at 25∘C, and enter your answer to one decimal place. ΔG∘=
The following reaction occurs in pure water: H2​O(I)+H2​O(I)⇄H3​O+(aq)+OH−(aq) which is often written as H2​O(I)⇄H+(aq)+OH−(aq) and has a value of ΔG∘=79.9 kJ/mol at 25.0∘C. Calculate the value of ΔG for this system under the following conditions at 25∘C and 1 atm. [OH−]=4.8×10−2M[H+]=8.9×10−1M​ (Enter your answer to three significant figures.)
