A student artificially pumped 1 mole of each substance seen below in a piston with a moveable lid (this lid can increase or decrease thereby changing the volume and pressure): 2 C3H7OH (g) + 902 (g) 6 CO2 (g) +8 H2O(g) If the student increased the volume of the piston, how will the reaction shift to reach a new equilibrium? No conclusion can be made since more information is needed The reaction will shift to the left The reaction will shift to the right The reaction will not shift because Q = K
