Julie blows a bubble. At first, the pressure of the gas in the bubble is 4kPa. the bubble floats into the air and expands. When it gets to the top of a tree the bubble has a pressure of 2pKa and a volume of 3.5m3. Assuming a constant temparture, what was the volume in m3 of the bubble when it was first blown?

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

i think it's c. i'm not sure but i think so.
