Multiple Choice

Use the following diagram to answer the next problem. An ideal heat engine uses 0.01 mol of gas and operates between a hot reservoir at
T_H = 400 K and cold reservoir at T_L = 300 K, in a cycle from a→b→c→d→a. From a→b the gas undergoes an isothermal expansion, changing its volume from Va to 2.5Va. From b→c, the pressure is reduced at a constant volume. From c→d, the gas undergoes an isothermal compression, and from d→a, the pressure is increased at a constant volume until the gas is back at the original condition at a.

-If the engine operates at 50 cycles per second,the power output is

• A)381 W
• B)45.8 W
• C)1145 W
• D)415 W
• E)1525 W
