A1.0 liter container is filled with 0.300 m of
pcl5 at 250◦c. the vessel is then held at a
constant temperature until the reaction
pcl5(g) ⇀↽ pcl3(g) + cl2(g)
comes to equilibrium. it is found that the
vessel contains 0.200 moles of pcl5. what is
the value of the equilibrium constant for the
reaction at this temperature?

24. a sports ball is inflated to an internal pressure of 1.85 atm at room temperature (25 °c). if the ball is then played with outside where the temperature is 7.5 °c, what will be the new pressure of the ball? assume the ball does not change in volume nor does any air leak from the ball a) 0.555 atm b) 1.74 atm c) 1.85 atm d) 1.97 atm

As air becomes more dense, (select all that apply) o. air weighs less o. gas molecules are closer together o. air is colder o. air weighs more o. gas molecules are further apart o. air is hotter
