You add B to a neat liquid of A in a dropwise fashion. A and B react in a bimolecular reaction step to form C, which precipitates. What order of the reaction will you observe, assuming the reaction to form C proceeds fast compared to the dropwise addition of A. Discuss why!

Solutions

Expert Solution

The sum of the powers of the concentration of the reactants in the rate law expression is called order of that chemical reaction.

The number of reacting species taking part in elementary reaction which must colloide simultaneously in order to bring about a chemical reaction is called molecularity of a reaction.

Bimolecular reactions involve simultaneous collision between two species,generally for bimolecular reactions the order will be Second order but if intermediate step is slow then it will be the rate determining step and it follows First order reaction,hence adding of B to A is a rate determing step and the order may be fractional or first order based on balanced chemical equation.

A laboratory group measures an excess of a volatile liquid. They add this to an empty flask with a volume of 56 mL. They heat the sample to 83.4 degrees Celcius until all the liquid is vaporized. The pressure in the lab is 0.987 atm. If 0.242 grams of volatile liquid were left in the flask, what was the molar mass of the compound? Record your answer to 2 decimal spaces.

At 300K, the vapor pressure of pure liquid A and liquid B are 37.33 kPa and 22.66 kPa respectively. If we mix 2 mol liquid A with 2 mol liquid B, the total vapor pressure above the solution is 50.66 kPa and the molar fraction of vapor A is 0.60. Assume the vapor is an ideal gas. Calculate (a) the activity of A and B in the solution (b) the Gibbs energy change of mixing ΔmixG (c) If the solution...
