Which equation represents the change that accompanies the standard enthalpy change of atomisation of iodine?
12I2(s)→I(g)\frac{1}{2}\text{I}_2(\text{s}) \rightarrow \text{I}(\text{g})21I2(s)→I(g)
I2(s)→2I(g)\text{I}_2(\text{s}) \rightarrow 2\text{I}(\text{g})I2(s)→2I(g)
12I2(g)→I(g)\frac{1}{2}\text{I}_2(\text{g}) \rightarrow \text{I}(\text{g})21I2(g)→I(g)
I2(g)→2I(g)\text{I}_2(\text{g}) \rightarrow 2\text{I}(\text{g})I2(g)→2I(g)
