Interpretation: The effect of adding
Concept introduction: According to LeChatlier's principle, when a dynamic equilibrium is subjected to a change in either concentration or temperature or pressure, then the position of equilibrium will shift in such a direction that it nullifies the change.
For example:
If concentration of A is increased by adding some more amount of A at equilibrium, then left side concentration is increasing, so to nullify this change, equilibrium shifts towards right side. Hence, forward reaction or formation of C is favoured in this case.

Explanation of Solution
The given equilibrium mixture described by exothermic equation is:
The exothermic equation represents that the thermal energy is removedfrom the reaction. So, the reaction can be rewritten as:
From the above equation it can be interpreted that heat is acting as a product so, heating the equilibrium mixture means adding more amount of heat to the system. Now, according to LeChatlier's principle, the equilibrium will shift in backward direction (reactant side as the product is increasing) in order to nullify the change. Thus, on raising the temperatureof the given exothermic equation, the concentration of reactants will increase and that of products will decrease and hence, resulting in decrease in

The exothermic equation represents that the thermal energy is removed from the reaction. So, the reaction can be rewritten as:
From the above equation it can be interpreted that heat is acting as a product so, lowering the temperature means cooling and the equilibrium mixture representsremoving amount of heat from the system. Now, according to LeChatlier's principle, the equilibrium will shift in forward direction (product side as the product is decreasing) in order to nullify the change.

- An expression for the root mean square velocity, vrms, of a gas was derived. Using Maxwell’s velocity distribution, one can also calculate the mean velocity and the most probable velocity (mp) of a collection of molecules. The equations used for these two quantities are vmean=(8RT/πM)1/2 and vmp=(2RT/M)1/2 These values have a fixed relationship to each other.(a) Arrange these three quantities in order of increasing magnitude.(b) Show that the relative magnitudes are independent of the molar mass of the gas.(c) Use the smallest velocity as a reference for establishing the order of magnitude and determine the relationship between the larger and smaller values.arrow_forwardThe reaction of solid dimethylhydrazine, (CH3)2N2H2, and liquefied dinitrogen tetroxide, N2O4, has been investigated for use as rocket fuel.
