Question 8

Which equation represents the process that occurs when the standard enthalpy of atomisation of iodine is measured?

A

I2(s)→2I(g)\text{I}_2(\text{s}) \rightarrow 2\text{I}(\text{g})I2​(s)→2I(g)

B

12I2(g)→I(g)\frac{1}{2} \text{I}_2(\text{g}) \rightarrow \text{I}(\text{g})21​I2​(g)→I(g)

C

12I2(s)→I(g)\frac{1}{2} \text{I}_2(\text{s}) \rightarrow \text{I}(\text{g})21​I2​(s)→I(g)

D

I(s)→I(g)\text{I}(\text{s}) \rightarrow \text{I}(\text{g})I(s)→I(g)
