Answer:
C. 2.
Explanation:
The total reaction order of this reaction is second order (2). For a second order reaction ,the rate depends on two variable concentration terms which may or may not be same.
Given that:
Two reactants combine to form a product in the reaction A + B → C
The above reaction is bimolecular as two molecules are involved in the reaction.
If and are the concentrations of A and B respectively at any time t, then assuming that the reaction is of first order with respect to both A and B , the overall order is second and the reaction rate is given by:
where;
= specific rate constant for a second order reaction and becomes the rate of the reaction when both and are unity.
Answer: Le Chatlier Principle
Explanation: Le Chatlier Principle states that if stress is being applied to an equilibrium, the reaction would move in hat direction in which the stress is been relaxed.
Thus the given reaction is
NO₂Cl(g) + NO(g) ⇄ NOCl(g) + NO₂(g)
When equilibrium is reached, some NO₂ gas is added to the container , now there will occur a change which will disturb the equilibrium, We can observe that the NO₂ is the one of the product constituent , thus addition of the same should have shifted to the equilibrium in forward direction. In order to nullify this, the equilibrium will shift in backward reaction.
Thus the equilibrium will shift in backward direction as the system returns to an equilibrium state at the same temperature.

Answer/Explanation:
The partial pressure of each gas in a mixture is proportional to its mole fraction. The pressure exerted by each gas in a gas mixture (its partial pressure) is independent of the pressure exerted by all other gases present. The partial pressure of an individual gas is equal to the total pressure multiplied by the mole fraction of that gas.
