Okay so in analytical chemistry question, where they asked us to identify the structural formulae contributing to the peaks I wrote the structural formulae but didn’t put a positive sign next to them, am I gonna lose marks?

In the part in Q2 about the percentage difference between k1 and k2, I wrote the formula but didn’t show any working regarding the difference between k1 and k2 or their average and straight up plugged the difference and average into the formula in the next step, am I gonna lose any marks?
