The principle that states that if a stress is applied to a system at equilibrium the system nullifies the effect of stress as far as possible MDCAT2024

One can estimate the direction in which equilibrium will shift with the help of MDCAT2023

One can estimate the direction in which equilibrium will shift with the help of MDCAT2022

During the manufacturing of nitric acid, NO is oxidized to nitrogen dioxide. This reaction is given as 

\( 2NO + O_2 \leftrightarrow 2NO_2  \    \Delta H = -114KJmol^{-1}    \)  

According to Le-chatlier's principle  MDCAT2015

When the pressure is applied over system ice ? water what will happen ? ETEA2019 [MP PMT 1990; CPMT 1983; NCERT 1978; DPMT 2002]

In the following reversible reaction \( 2SO_2 + O_2 \rightarrow 2SO_3 +QCal \)  Most suitable condition for the higher production of SO₃ is [NCERT 1974; DPMT 1983, 89; IIT 1981; MP PET 1992; MP PMT 1990, 91, 94, 99; CPMT 1973, 77, 84, 89, 94, 99]

Which of the following reactions proceed at low pressure [MP PET 1985; CPMT 1984; MP PMT 1995; RPMT 1997]

In the above reaction which is the essential condition for the higher production of NO [CPMT 1971, 89; MP PMT 1985]

When in any system at equilibrium state pressure, temperature and concentration is changed then the equilibria shifted to such a direction which neutralize the effect of change. This is known as [MP PMT/PET 1988; DPMT 1985]
