Utilizing data to compute the nonstandard emf for each of the following reactions if the concentration of each of the ions in these reactions is 0.0002 molar as well as everything else is standard use 298 K for the temperature, R = 8.314 J/mol-K, and F = 96,485 C/mol:
(a) 1 Fe2+(aq) + 1 Ni(s) --> 1 Fe(s) + 1 Ni2+(aq) E =____ V(b) 1 Br2(l) + 1 Cd(s) --> 2 Br-(aq) + 1 Cd2+(aq) E =_____ V(c) 2 Fe(CN6)3-(aq) + 2 Cl-(aq) --> 2 Fe(CN6)4-(aq) + 1 Cl2(g) E =____ V(d) 1 F2(g) + 1 Hg22+(aq) --> 2 F-(aq) + 2 Hg2+(aq) E = ____ V
This given reaction: 2 O3(g) -→ 3 O2(g) has an empirically determined rate law (with a single unimolecular event). Determine what is the observed rate If k =4.0 × 105s-1, [O2] = 0.2M and [O3] = 0.5 M?
130 ml of an hcl solution with ph of 3.90 is added to 200 ml of an hno3 solution. the resulting solution is 1.40. what
One method used to store energy during times of low demand is by pumping water uphill into a reservoir. When energy demand exceeds the output produced by power plants, the water is released, moves downhill, and is converted into electricity by a t..
