Temperature effect on the reaction

[Fulminate]

Hello,
I haven't figured out what would be the effect of temperature change on this reaction, and why so. Thanks for any hint!

2CaCO₃(s) + 2SO₂(g) + O₂(g) → 2CaSO₄(s) + 2CO₂(g)

Personally, I have thought about using the Gibbs free energy, but this would only tell me if the reaction is nonspontaneous (i.e., and the input of external energy is necessary for the reaction to occur) and then it is spontaneous (occurs without external energy input)

Once again, I really appreciate any of your ideas and hints

Figur out if the reaction is exothermic or endothermic.
If exothermic equilibrium shifts left, if endothermic it shifts right, if temperature is increase.

I was considering calculating the Gibbs, but that would only reveal whether the reaction is not spontaneous.
