in equilibrium only gases are involved the products contains (S) only as gas so removing some (S) would decrease the concentration of the product and hereby making the reactant species more concentrated. Equilibrium position always moves from high concentration to low concentration . so the equilibrium position will shift from roght to left favouring the fromation of (R)
Reducing the temperature, favours the forward reaction i.e more product formation
