A chemistry student needs to determine the effect of an increase in temperature on the equilibrium concentration of products and reactants for the reaction N2(g) + 3H2(g) ⇌ 2NH3(g). Calculate the new concentration of NH3 at equilibrium when the temperature is raised from 300 K to 400 K.

A chemistry student needs to calculate the new value of the ionization constant (Ka) of a weak acid when the temperature is raised from 25°C to 45°C, given that the initial value of Ka is 1.8 x 10^-5 at 25°C and the enthalpy of ionization (ΔHion) is 50.2 kJ/mol.
