2Cl2O7(g)
2Cl2(g)
+7O2(g)
Entropy is degree of randomness,or disorder,more disorder means larger the entropy
The number of particles increases ,that is 2 moles of Cl2O7(g) decomposes to total 9 moles of gaseous product that is 2 moles of Cl2(g) and 7 moles of O2(g),so disorder increases
S=[Sum
of entropy of product]-[Sum of entropy of reactant]
Entropy of product will be higher than that of reactant because
more number of gaseous moles are there in the product side ,so more
disorder it will become,so
S is positive for the process.
Answer=S
is positive for the process
