Question

Where possible, classify these systems as reactant-favored or product-favored at 298 K. If the direction cannot be determined from the information given, classify the reaction as "Insufficient information".

a.) 2A(g)+B(g) ----> C(g)
                        <----
    Delta H = +235KJ
b.) 2A(g)+B(s) ----> C(g)
                        <----
    Delta H = -193KJ

c.) A(g)+B(g) ----> C(g)
                        <----
    Delta H = -97KJ

d.) 2A(g)+2B(g) ----> 5C(g)
                        <----
    Delta H = +313KJ

Explanation / Answer

In general, product-favored reactions are exothermic,

So b and c are product favoured.

Insufficient information for the a and d options
