The following reaction occurs in pure water: h2o(l) + h2o(l) h3o+(aq) + oh-(aq) which is often written as h2o(l) h+(aq) + oh-(aq) and has a value of ∆g° = 79.9 kj/mol at 25.0°c. calculate the value of ∆g for this system under the following conditions at 25°c and 1 atm. [oh-] = 2.5×10-1m [h+] = 9.5×10-1m.
