(i) Is the system in equilibrium? If not, which direction must the reaction proceed for equilibrium to be established? (ii) What is the Kp for this system at equilibrium?
The standard free energy for the neutralization of HCl with NaOH at 25 degrees celsius is -79.9KJ/mol. Calculate the equilibrium constant for the reaction.
A solution is prepared by mixing 250 mL of 1.00 M CH3COOH with 500 mL of 1.00 M NaCH3COO.
Working with triple point, The sublimation pressures of solid chlorine are 352 Pa at -112 C and 35 Pa at -126.5 C. The vapor pressures of liquid Chlorine are 1590 Pa at -100 C and 7830 Pa at -80C
A sports beverage company is seeking an energy supplement to increase the performance of the athletes. An ongoing research project suggest the use of a tetrasaccharide with the following characteristics
Geologists can estimate the age of rocks by their uranium-238 content. The uranium is incorporated in the rock as it hardens and then decays with first-order kinetics and a half-life of 4.5 billion years. A rock is found to contain 84.3% of the am..
