Q. We don't have a study room booked, but we see one that is empty. Can we use it?

Maybe. Our policy for room bookings is that the reservation holds for 10 minutes from the start time. You can check to see if the room is booked through Online Room Bookings. If it is booked and it is 10 minutes after the booking should have started, then go to the checkout counter and explain that you would like to book it yourself. If it is not booked - then Book it Now for your group!
