@X@user.full_name@X@ @GMU: After 74.372 seconds the concentration of A was reduced from 0.3071 M to 0.2286 M. What is the first order rate constant?

@X@user.full_name@X@ @GMU: How much energy in kJ is released to form one mole of 191Ir from protons, electrons, and neutrons if the nucleus has a mass of 190.960584 amu? The masses of the proton, electron and neutron are 1.00728 amu, 0.000549 amu and 1.00867 amu, respectively.

@X@user.full_name@X@ @GMU: What would the be after addition of 5.94 mL of 0.1000 M NaOH to 25.00 mL of 0.1000 HA (a weak acid, Ka = 2.12e-4)?

@X@user.full_name@X@ @GMU: NO2 at 378°C decomposes to form NO and O2 according to second order kinetics (see reaction below). The half-life for this reaction was measured to be 3.16e1 s when the initial concentration of NO2 was 7.73e-3 M. What is the rate constant for this reaction?2NO2(g) → 2NO(g) + O2(g)
