Question 4

Which equation represents the chemical change that occurs during the standard enthalpy change of atomisation of bromine?

A

Br2(l)→2Br(g)\text{Br}_2(\text{l}) \rightarrow 2\text{Br}(\text{g})Br2​(l)→2Br(g)

B

12Br2(g)→Br(g)\frac{1}{2}\text{Br}_2(\text{g}) \rightarrow \text{Br}(\text{g})21​Br2​(g)→Br(g)

C

12Br2(l)→Br(g)\frac{1}{2}\text{Br}_2(\text{l}) \rightarrow \text{Br}(\text{g})21​Br2​(l)→Br(g)

D

Br2(g)→2Br(g)\text{Br}_2(\text{g}) \rightarrow 2\text{Br}(\text{g})Br2​(g)→2Br(g)
