I am pretty sure that the effect on the volume of 1 mol of an ideal gas is being revelesd by the option : B. The pressure changes from 760 torr to 202 kPa, and the temp. changes from 37degrees C to 155 degrees kelvin. I choose this one because you have to use ideal gas law - V= nRT/P and you will see the doubled pressure in here : <span>760 torr= 1atm and 202kPa = 2 atm. Do hope it helps! Regards.</span>
The concentrations of a mixture at equilibrium are constant as a function of time because the <span>e forward reaction proceeds at the same rate as the reverse reaction.</span>
