Answer 2

A OR B

Answer 3

Equilibrium constant, by Le Chatelier's principle, will be affected by change in concentration definitly

if the reaction proceeds in a reduction of no. of molecules like
N2+3H2 --> 2NH3
i.e. 4 molecules react to give 2 molecules
then change in pressure influences the Equilibrium constant and also the direction of the reaction.

if the reaction proceeds in a liberation or absorption of energy like
2CO + O2 --> 2CO2 + 121kJ of heat.. ( the value of heat is an example)
i.e. heat is liberated
then change in teperature influences the Equilibrium constant and also the direction of reaction.

hence all the options are true.

Answer 4

A or B change the EQUILIBRIUM CONSTANT. Reactant and product concentrations change each other, but not the constant.
