Pearson Edexcel IAL Chemistry syllabusChemistry YCH11First assessment 2019
For the sole direct task, explain that chlorine molecules diffuse into the second jar, become more dispersed and therefore occupy a higher-entropy arrangement.
How this is tested
- Explain spontaneous chlorine diffusion through greater molecular dispersal and entropy.
