A Level H2 Chemistry 2021 Paper 3 Answers

Analyzing the effect of temperature on gas volume and determining the most likely chemical equation based on experimental ratios.

For non-spontaneous: ΔG° > 0 ΔH° – TΔS° > 0 ⇒ –57,200 – T(–175.8) > 0 –57,200 + 175.8T > 0 175.8T > 57,200 T > 325.4 K (2 marks – inequality setup & final T) A Level H2 Chemistry 2021 Paper 3 Answers
