The dimerization of NO2(g) to N2O4(g) is an endothermic process. Which of the following will, according to Le Châtelier's principle, increase the amount of N2O4 in a reaction vessel?

Correct Answer: Making the reaction vessel smaller
(D) The reaction is: HEAT + 2 NO2(g) ? N2O4(g)

In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.

Two vessel P and Q contain milk and water in ratio 3 : 2 and 5 : 3 respectively. If 10 liters of the mixture is removed from vessels P and poured in vessel Q then ratio of milk to water in vessel Q becomes 8 : 5. Find the initial quantity of water in vessel Q.

A vessel of capacity 2 litre has 25% alcohol and another vessel of capacity 6 litre had 40% alcohol. The total liquid of 8 litre was poured out in a vessel of capacity 10 litre and thus the rest part of the vessel was filled with the water. what is the new concentration of mixture ?

50°C তাপমাত্রায় N2O4 বিয়োজনের KP এর মান 3.11 atm । সাম্যমিশ্রনে NO2 এর আংশিক চাপ 0.45 atm হলে N2O4 এর আংশিক চাপ কত?

298K তাপমাত্রায় সাম্যবস্থায় N2O4 এর বিয়োজন মিশ্রণে N2O4 এর আংশিক চাপ 0.8 atm এবং বিক্রিয়াটির Kp= 0.008 atm। NO2 এর আংশিক চাপ নির্ণয় কর।

For the reaction, A = X + Y, the respective concentrations are CA, CX and CY. The forward reaction rate constant is kf and the backward reaction rate constant is kb. Choose the correct statement from the following:
P. At equilibrium, kf CA > kB CxCy
Q. If the reaction is irreversible than, kb CXCY = 0
R. The backward reaction rate will essentially be first order, if the forward reaction rate is first order.
S. Activation energy for the first order forward reaction will be independent of temperature.

Which of the following are major principles of leading?
1. Principle of motivation
2. Principle of continuous development
3. Principle of harmony of objectives
4. Principle of open competition
5. Principle of communication clarity
Select the correct answer:

For a reaction, the extent of reaction equation is Ni = Nio + ϒVi is Where: Ni = Moles of species I present in the system after the reaction occurs Nio = Moles of species I present in the system when the reaction starts Vi = Stoichiometric coefficient for species i in the specified chemical reaction equation ϒ = Extent of reaction

Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is
