Question

At 25°C, 50 g of iron reacts with HCl to form FeCl . The evolved hydrogen gas expands against a constant pressure of 1 bar. The work done by the gas during this expansion is (Round off to the Nearest Integer). [Given: R=8.314 J mol K . Assume, hydrogen is an ideal gas] [Atomic mass of Fe is 55.85 u] 2 –1 –1
