Question

What can change the direction of a reversible reaction involving gases?

A. Change in temperature
B. Change in pressure
C. Change in volume
D. All the above
E. None of the above

Answer 1

The correct option is: D. All the above

Step-by-step explanation:

Le Chatelier's principle suggests that any change in the various reaction conditions including concentration, temperature, pressure and volume; of the given chemical reaction at equilibrium, affects the equilibrium of the reaction. Thus causing the equilibrium to shift in the direction that minimizes the effect of the change.

For a reaction involving gaseous molecules, any change in the volume, pressure, concentration and temperature; greatly affects and changes the direction of the equilibrium towards the reactants or the products.
