In this synthesis reaction, what product will form?
h2(g)+ci2(g) >

a. 2h(g)+2ci(g)
b. 2hci(g)
c. ci2(g)+h2(g)
d. h2o(i)+hci(g)

ps. the numbers in c & d are smaller & they are also smaller in the question.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

You know how the first one if filled up like the objects do the same but with the other categories
