Without any calculations what is the Entropy Change? i.e. positive, negative, or approx zero

SO2(g) + ½O2(g) => SO3(g) negative
CO(g) + ½O2(g) => CO2(g) negative
2CO(g) + O2(g) => 2CO2(g) negative

Not entirely sure about these though

Yes. When the number of molecules decreases in the reaction, it is very likely that entropy decreases because the system is becoming more ordered and entropy is a measure of disorder.
