Answer:

Solution:-

The gas is in the standard temperature and pressure condition i.e. at S.T.P

Therefore,

=?

As given that the expansion is isothermal and reversible

∴ΔU=0

Now from first law of thermodynamics,

ΔU=q+w

∵ΔU=0

∴q=–w

Given that the heat is absorbed.

∴q=1000cal

⇒w=−q=−1000cal

Now,

Work done in a reversible isothermal expansion is given by-

w=−nRTln(

Given:-

T=0℃=273K

n=1 mol

∴1000=−nRTln(

What is the value for ΔSºreaction for the following reaction, given the standard entropy values?
Diano4ka-milaya [45]
Substituting the values:

51 + 3(131) = ΔH + 2(28) + 3(189)
ΔH = -225 J/mol

When written outside of the equation, this becomes 225 J/mol
