2. a) Find the overall order of the following irreversible reaction: 2H₂ +2NO→N₂ + 2H₂0, from the following constant volume data (i.e data collected in a constant volume bomb) obtained by using equimolar quantities of hydrogen and nitric acid, Take T=296K. Half life(seconds) 265 186 115 104 67 Total Pressure(mm Hg) 200 240 280 320 360

c) Write the differences for integral and differential method

b) Nitrous oxide decomposes according to the second order rate equation 2N₂0→2N₂ +0₂ The rate constant is 977 cm³/ (mol. s) at 895°C. Calculate the fraction decomposed at 1s, 10s, and at 10 min in a constant volume batch reactor. The initial pressure (all N₂O) is 1 atm.

a) For a gas reaction at 400K, the rate is reported as -dPA/dt= 3.66 PA^2. What is the value of rate constant for this reaction if the rate equation is measured in terms of mol/ (l. h)?

The indicating liquid in the manometer shown in the figure below is water and benzene with a density of 880 kg/m³. These two liquids are essentially insoluble in each other. If the two liquids are essentially insoluble in each other. If the manometer reading is ΔZ = 37.19 cm of water, what is the pressure difference P₁ - P₂ in kN/m². Show detailed calculations.

A mixture containing 10% ethanol (E) and 90% H₂O (W) by weight is fed into a distillation column at the rate of 106.26 kg/h. The distillate (top product) contains 94.01 % ethanol and the distillate is produced at a rate of one tenth of that of the feed. 

_{Draw and label a flow chart of the process before solving the problem. Perform material (total) and ethanol balances to calculate the mass fraction of ethanol in the bottom product to at least four decimal places.} 

The indicating liquid in the manometer shown in the figure below is water and benzene with a density of 880 kg/m3. These two liquids are essentially insoluble in each other. If the two liquids are essentially insoluble in each other. If the manometer reading is AZ = 43.99 cm of water, what is the pressure difference P1 - P2 in kN/m2.

Please show detailed calculation.

One liter per minute of liquid containing A and B (CAo=0.10 mole/liter, CBo= 0.01mole/liter) flow into a mixed flow reactor of volume V-1 liter. The materials react in a complex manner for which the stoichiometry is unknown. The outlet stream from the reactor contains A, B and C (CA 0.02 mole liter, Cu 0.03 mole liter, Cer=0.04 mole/liter). Find the rate of reaction of A, B and C (ie, rA,rB,rC and to) for the conditions within the reactor? Explain problem with step by step briefly?
