At $2 7^{\circ} C$ , one mole of an ideal gas is compressed isothermally and reversibly from a pressure of 2 atm to 10 atm . The values of DE and q are ( $R = 2$ )

Options:

Answer:

Solution:

$W = 2.303 n RT lo g \frac{P _{2}}{P _{1}} = 2.303 \times 1 \times 2 \times 300 lo g \frac{10}{2} = 965.84$

At constant temperature, $Δ E = 0$ .

$Δ E = q + w$

$q = - w = - 965.84 c a l$
