Can you help me correcting this questions in the picture with the notes below please? Notes: In question 1a, the rate law is fine but should have partial pressures, not concentrations. In 1b, the units of the answer are incorrect; they should have "atm" in it. Hint: in the denominator of the calculation is atm^3.
