A second order reaction of the type A + B--> P was carried out in a solution that was initially .075 mol dm^-3 in A and .050 mol dm^-3 in B. After 1.0 h the concentration of A had fallen to .020mol dm^-3 a)Calculate the rate constant b)What is the half life of the reactants
What is the pressure (in atm) inside a container of gas connected to a mercury filled open-end manometer when the level in the arm connected to the container is 28.3cm higher than the level in the arm open to the atmosphere,
Find the nuclear binding energy of uranium-234 (atomic mass = 234.040947 amu) in utits of joules per nucleon. (Data: neutron mass = 1.674928 x 10^-24 ; proton mass = 1.672623 x 10^-24; Avogadro's Number = 6.0221367 x 10^23; c = 2.99792458 x 10^8)
