A flask has a volume of 71.9ml. It is filled with water vapour at pressure of 1053.8 kPa and temperature of 738 k. The mass of water vapour in the flask is

Qand k are only the same when the forward rate of the reaction has reached zero.

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:
