A gas container with a fixed volume has a pressure of p atm. Gas is then added to the container so that the number of gas particles is the container doubles. What happens inside the container? pressure doubles because the frequency of collisons doubles pressure decreases because there are more collisions between gas particles inside the container pressure increases because the force of the collisions increases temperature increases because the particles are moving faster
if the transition state has a smaller volume than the reactants (deltaV double dagger
