Ionic Dissociation

Postby 605168557 » Sat Mar 16, 2019 12:33 pm

Can someone explain the steps for this problem please? The ionic dissociation of water is given by the following reaction: The standard enthalpy for the reaction is 58 kJ. mol-1. The Kw for the reaction at 25 degrees Celsius is 10^-14. Is a pH of 7 acidic or basic at 10 degrees Celsius? The reaction is 2H2O (l) ---> H3O+ (aq) + OH- (aq)

With this question, you have to use the vant hoff equation. The question gives the unknowns except for K. You can solve for K, and they put that back into the original balanced equation and solve for conc of h30+
