A pistion filled with 0.04 mol of an ideal gas expands reversibly from 50 mL to 375 mL at a constant temperature of37°C. As it does so, it absorbs 208 J of heat. The values of q and w of the process will be
R = 8.314  Jmol -1 K -1 In 7.5 = 2.01

Options:

Answer:
A
Solution:

The process is isothermal expansion, so
q=-w{∵Δu=0}
Since, q = + 208 J
w = −208 J(expansion work)
