"Unlike reformed GCSEs (which will use a 9 to 1 grading scale), we’re keeping the current A* to E grading system for reformed A levels (A to E for reformed AS). So what’s the challenge?First, the A* grade. The current rule is based on A levels that are made up of AS and A2 units. In reformed linear A levels, there is no need for such a complex rule, and no need for a ‘uniform mark scale’ either. A* will be another grade boundary that can be set by senior examiners (as for A and E) or set arithmetically (as for B, C and D)." https://ofqual.blog.gov.uk/2015/08/14/a-level-awarding-in-2016-and-2017/

i got 88.8% recurring for the percentage and 88.8recurring% of 9 is exactly 8, also the rate was reduced because less molecules less likely to undergo successful collisions

Someone in the other unofficial markscheme thread is saying that the concentration was higher so there was an increase in successful collisions. Do you remember that?
