20. Solving a chemistry problem

9. Calculate ΔG ΔS ΔH at 20 C for the reaction occurring in the Weston element, if the dependence of the emf on temperature is expressed by the equation: E = 1.0183-4.06*10-5*(T-20 C). Describe the device, recording circuit, electrode reaction, scope of application of the hydrogen electrode (in an acidic environment).
