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) + 3b(g) --> 4c(g) delta h = -95kj b)2a(g) + 2b(g) --> 3c(g) delta h = 254kj c)2a(g) + b(g) --> 4c(g) delta h =322 kj d)2a(g) + b(g) --> 3c(g) delta h -193kj i thought that a)reactant favored, b) reactant favored, c) product favored, and d) insufficient information because that in a and b there are more reactant than products and in c there are more products than reactant and d is equal amount. but i got the answer wrong. could someone explain to me?
