What is the sign of the entropy change for the system when the reaction below proceeds from reactants to products? N2O4(g) ------> 2 NO2(g)
Homework Answers
Answer: + positive sign
Explanation: Entropy is a measure of disorderness. Since 1 mole reactant gives 2 moles of product. hence entropy increases. Like when NaCl salt dissolves in H2O the NaCl dissociates into 2 ions therby entropy decreases.
