Here is a question for a chemistry student to solve in the subtopic Calculation of current density in an electrochemical cell: What is the current density (in amperes per square meter) in a zinc-copper galvanic cell, given that the mass of zinc electrode is 10 g and the rate of zinc dissolution is 0.1 g/min, the area of copper electrode is 5 cm², and the potential difference between the electrodes is 1.5 V?

If the equilibrium constant (Kc) for the reaction N2(g) + 3H2(g) ⇌ 2NH3(g) at a certain temperature is 4.0×10^-3, and a catalyst is added to speed up the reaction, how will the equilibrium position shift? Calculate the new equilibrium constant if the catalyst increases the rate of the forward reaction by a factor of 10.
