Evaluation - equilibrium - Le chatlier Principle

Question 1: The principle which governs the effect of temperature or pressure on equilibrium reaction is called ----------





Question 2: The change in any of the factors that determine the equilibrium conditions of a system will cause the system to change in such a manner so as to reduce or to counteract the effect of the change. Which is the principle?





Question 3: H2(g) + I2(g) ⇋ 2HI(g) what happens to the reaction when the concentration of Hydrogen increases





Question 4: If we increase the pressure of the system CO(g) + 3H2(g) ⇋ CH4(g) + H2O(g)





Question 5: 2NO2(g) ⇋ N2O4(g); ∆H = –57.2 kJ mol–1 for the reaction what happens when the temperature is increased?
