31. N2(g) + 3H2(g) ⇌ 2NH3(g) ∆H = − 92 kJ mol-1 How does the use of a catalyst affect the amounts of N2, H2 and NH3 present in the equilibrium mixture. 32. N2(g) + 3H2(g) ⇌ 2NH3(g) ∆H = − 92 kJ mol-1 How does a higher temperature affect the amounts of N2, H2 and NH3 present in the equilibrium mixture. 33. N2(g) + 3H2(g) ⇌ 2NH3(g) ∆H = − 92 kJ mol-1 How does lower pressure affect the amounts of N2, H2 and NH3 present in the equilibrium mixture. 34. NO2, is a brown ga...

This OCR A Level chemistry excel sheet is the perfect revision tool and contains every specification point in question and answer format, encouraging the use of active recall in revision. It is editable and should save you from having to make any notes. Mark scheme key points have also been added. the preview may not show the entire document since it is in excel format but once downloaded you will have two columns - left one with questions and the right one with all the answers and details :)
