Hello,
Quick question as I know there are some of you about.
Do you teach the acid or alkali hydrogen fuel cell or both?
The spec doesn’t say one way or the other just that higher tier should be able to write half equations.
Our text book shows the alkali one but other resources show the (easier) acid one.
Has anyone seen a past paper question and mark scheme on this? I’d be interested to see what the exam board will accept as correct.
Thanks so much!
