What is the time to equilibrium? When the concentration in the environment is set to 90% the cell reaches equilibrium in 55 seconds 3- Under which set of conditions does the cell reach equilibrium with its environment the slowest? What is the time to equilibrium? When the concentration in the environment is set to 10% the cell reaches equilibrium after 76 seconds 4- In each of the three simulations, is the net movement of solute into or out of the cell?
