When you do get access to the mark scheme, do not just check the final number. Look at how the marks are awarded for intermediate steps.
If your sheet involves finding orders of reaction from a table of initial rates:
Based on the Chemsheets A2 1079 structure, here is how a problem is calculated: Initial Moles: Equilibrium Moles: Total Pressure: Total Moles: Mole Fractions: Partial Pressures (MPa): Kpcap K sub p Expression:
Partial Pressure (pA)=xA×Total Pressure (Ptotal)Partial Pressure open paren p sub cap A close paren equals x sub cap A cross Total Pressure open paren cap P sub total end-sub close paren The Kpcap K sub p
