Question

Two moles of an ideal gas expands isothermally reversibly from 1l to 15l at 300 k calculate the delta U for reaction

Answer 1

Answer:

i don't know the solution

Answer 2

The internal energy for the given reaction is 0 J/mol

Explanation:

To calculate the internal energy for isothermal reversible expansion, we use the equation:

$\Delta U=nC_v\Delta T$

where,

$\Delta U$ = internal energy for a reaction

n = number of moles of gas = 2 moles

$C_v$ = heat capacity at constant volume = ?

$\Delta T$ = change in temperature = 0    (for isothermal process)

Putting values in above equation, we get:

$\Delta U=2\times C_v\rimes 0\\\\\Delta U=0J/mol$
