Suppose you carried out the decomposition reaction using 30.0 mL of reaction solution (i.e. 15.0 mL of 6.10% hydrogen peroxide and 15.0 mL of the solvent, water). Assume that you observed the pressure increase by 0.148 atm over a period of 20.0 seconds at a constant temperature, 20.5ºC.
A. How many moles of oxygen gas are produced in 20.0 seconds? (Conversion factor = 0.1545 M/atm)
B. What would be the concentration of oxygen (in molarity units) if the gas had remained in the solution?
C. Based on the above data, what is the rate of formation of oxygen (in units of molarity per second)? What is the rate of the reaction? (different than the formation of oxygen)?

Please answer #3!
You will be using 25.00 mL of 3.00% by mass solution ({mass H_2O_2/ mass solution}*100) of hydrogen peroxide. Assume the density of this solution is 1.000 g / mL. If all hydrogen peroxide decomposes to water and oxygen according to the reaction 2H_2O_2 (aq) 2H_2O (I) + O_2(g) What is the total volume of the oxygen gas generated if the temperature is 24 degree C and the pressure is 770 Torr (760 Torr = 1 atm) ?...

Please answer and explain thoroughly
Suppose we were able to measure the amount of oxygen gas formed in units of moles/L, and the rate of formation of oxygen was found to be 0.0125 M/s. Using the rate law for this reaction and the units associated with each variable, show what the derived units for the rate law constant would be. What would be the rate of decomposition of the hydrogen peroxide? Explain your answer.
