Assuming a chemical equilibrium reaction aA + bB ⇌ cC + dD, with initial concentrations of [A] = 0.2 M, [B] = 0.3 M, [C] = 0 M, and [D] = 0 M at 25°C, what will be the new equilibrium concentration of [B] if the volume of the container is decreased to half the original volume?

A metal electrode immersed in a solution is used to convert a chemical reaction into an electric current. The electrode potential is measured as the voltage difference between the metal and the solution. The cathodic and anodic Tafel slopes are then calculated in order to determine the rate of the chemical reaction occurring at the electrode. Given a metal electrode immersed in a 0.1 M solution of AgNO3, the cathodic and anodic Tafel slopes are determined to be 120 mV/decade and 110 mV/decade, respectively. Calculate the exchange current density for the reaction occurring at the electro
