In a closed industrial vessel, sulfur dioxide gas reacts with oxygen to establish a reversible reaction producing sulfur trioxide:
2SO2(g)+O2(g)⇌2SO3(g) 2\text{SO}_2(\text{g}) + \text{O}_2(\text{g}) \rightleftharpoons 2\text{SO}_3(\text{g}) 2SO2(g)+O2(g)⇌2SO3(g)Eventually, this system reaches a state of dynamic equilibrium.
State what is meant by the term dynamic in this context.
Practise Edexcel GCSE Chemistry Reversible reactions and equilibria with exam-style questions for Foundation and Higher tier. 38 questions, matched to the Edexcel GCSE Chemistry (1CH0) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
