Aglass container was initially charged with 4.50 moles of a gas sample at 3.75 atm and 21.7
some of the gas was released as the temperature was increased to 28.1 °c, so the final
pressure in the container was reduced to 0.998 atm. how many moles of the gas sample are
present at the end?

Compare the equilibrium constants for the systems shown in the table. which favors products the most? which favors products the least? rank these systems in order from most to least in terms of favoring products rather than reactants. d > b > a > c c > a > b > d b > c > d > a a > d > c > b

Ineed to find the answer of this question because i dont understand it
