Calculate the partial pressure (in atm) of HBr at equilibrium when 5.00 atm of CH3Br and 5.00 atm of H2O react at 1000 K according to the following chemical equation:
CH3Br (g) + H2O (g) ? CH3OH (g) + HBr (g) Kp = 6.93×10-2
A piston has an external pressure of 11.0 rm atm. How much work has been done if the cylinder goes from a volume of 0.130 liters to 0.460 liters.
What is the pH of 1.0 x 10^-4 M phenol where ka = 1.3 x 10^-10? This is a weak acid under dilute conditions. You need to take into account water self-dissociation to find the hydronium concentration.
