For the chemical reaction, Li + NaCl <-- --> Na + LiCl, the rate law would be...
1 answer:
<u>Answer:</u> The rate law for the given chemical equation is
<u>Explanation:</u>
Rate law is defined as the expression that expresses the rate of the reaction in terms of the molar concentration of all the reactants each term raised to the power their stoichiometric coefficient in the given balanced chemical equation.
For the given balanced chemical equation:
Rate law expression for the reaction:
Order with respect to Li = 1
Order with respect to NaCl = 1
Hence, the rate law for the given chemical equation is

Answer:
a)
b) entropy of the sistem equal to a), entropy of the universe grater than a).
Explanation:
a) The change of entropy for a reversible process:
The energy balance:
If the process is isothermical the U doesn't change:
The work:
If it is an ideal gas:
Solving:
Replacing:
Given that it's a compression: V2<V1 and ln(V2/V1)<0. So:
b) The entropy change of the sistem will be equal to the calculated in a), but the change of entropy of the universe will be 0 in a) (reversible process) and in b) has to be positive given that it is an irreversible process.
