Why an open sentence always has at least one variable?
An open sentence is neither true nor false. It depends on the value of the variable. If you had 5=3 that would be a closed sentence which is false. If you had 5=5 that would be a closed sentence which is true. If you had x=3 then it is open to whether the x is a 5 or a 3.

Is it true that an example of a stress on an equilibrium is the increase of pressure in a closed system when the pressure of a reactant gas is increased from 1.0 ATM to 2.0 ATM?
Yes, increasing the pressure of a reactant gas in a closed system at equilibrium will shift the equilibrium towards the side with fewer moles of gas molecules to counteract the increase in pressure. This is in accordance with Le Chatelier's principle, which states that a system at equilibrium will adjust to counteract any external stress applied to it in order to reestablish equilibrium.
