Consider the reaction:

a(g) + b(g) ? c(l)

in order for a reaction to be spontaneous under standard conditions, the reaction must:

result in an increase of the entropy of the system

this reaction could not be spontaneous under standard conditions

be exothermic

take place at high temperatures

take place in the presence of a catalytst

What are the spectator ions in 2h+ + so42- + ca2+ + 2r → caso4 + 2h+ + 21?
