Question

Which of the following processes would you predict to have a positive value for º ? 2SO2(g) + O2(g) → 2 SO3(g) P4O10(s) + 6H2O(l) → 4H3PO4(s) 2POCl3(g) → 2PCl3(g) + O2(g) 2H2(g) + O2(g) → 2H2O(l)

Answer 1

The answer is C in plato

Answer 2

`2POCl_3(g) --> 2PCl_3(g) + O_2(g)`

Step-by-step explanation:

Hello,

For the listed chemical reactions, one can predict the one which has a positive ΔS° is:

`2POCl_3(g) --> 2PCl_3(g) + O_2(g)`

This is foreseen owing to the greater number of products (2) by contrast with the number of reagents (1). Moreover, for such reaction, there is a greater amount of moles at the products than at the reagents.

Best regards.
