What does Le Châtelier's principle state?
O
A. A reaction at equilibrium will go to completion when the
equilibrium is upset.
O
B. A reaction at equilibrium will respond to balance a change.
O
C. A reaction will form a new equilibrium ratio when the equilibrium is
upset.
O
D. A reaction at equilibrium will not respond to a change.

B. A reaction at equilibrium will respond to balance a change.

Explanation:

The Le Chatelier's principle states that a reaction will respond to balance a change. This is true for a reaction in chemical equilibrium.

Le Chatelier's principle sates that "if any conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
