Solution: Ethene (C2H4) can be halogenated by the following reaction: C2H4(g) + X2(g) ⇌ C2H4X2(g), where X2 can be Cl2, Br2, or I2.Does higher temperature make the reactions more spontaneous or less spontaneous

Problem

Ethene (C2H4) can be halogenated by the following reaction: C2H4(g) + X2(g) ⇌ C2H4X2(g), where X2 can be Cl2, Br2, or I2.

Does higher temperature make the reactions more spontaneous or less spontaneous?
