Question

Work done during isothermal expansion of one mole of an ideal gas from 10 atom. to 1 atm at 300K is.

• A. 4938.8 J
• B. 4138.8 J
• C. 5744.1 J
• D. 6257.2 J

Answer 1

Answer: (C)

5744.1 J

Answer 2

Given that

$- 286kJ/mole$, $2H_{2}O_{2}(l) \rightarrow 2H_{2}O(l) + O_{2}(g)$, $- 196kJ/mole$, $146kJ/mole$

$- 494kJ/mole$

Now, by using

$- 98kJ/mole$

$(\Delta H_{t})$

$C(xzsQkbV) + O_{2}(g) \rightarrow CO_{2}(g);\Delta H = xkJ$
