In 1.00 atm of pure oxygen, the solubility of O2(g) in water is 1.26 x 10^-3 M at 25.0 degree C. The mole fraction of oxygen in air is 0.210. If the atmospheric pressure is 0.979 atm, what is the solubility of oxygen in air at 25.0 degree C?
If the half-life of a first-order reaction is 4.609 hours what is the instantaneous rate of the reaction in M/day when the concentration of A equals 0.251 M?
The linear form (y=mx+b) of the Arrhenius equation is given below : ln K = -Ea/RT + Ln A 1) In order to find the activation energy (Ea) you will need to make a linear graph
