The following equilibrium reaction takes place at 179c. 2 so2(g) o2(g) equilibrium reaction arrow 2 so3(g) if the amount of so3 gas is exactly 0 mol at the start of the reaction and 2.11 ? 10?4 mol when the reaction reaches equilibrium, calculate the change in the number of moles of each gas from the start of the reaction to the equilibrium stage. (a positive sign indicates an increase in an amount; a negative sign indicates a decrease in an amount)
A) SO2: -2 moles, O2: -1 mole, SO3: +2.11 x 10-4 moles
B) SO2: -2 moles, O2: -2 moles, SO3: +2.11 x 10-4 moles
C) SO2: -1 mole, O2: -1 mole, SO3: +2.11 x 10-4 moles
D) SO2: -1 mole, O2: -2 moles, SO3: +2.11 x 10-4 moles
