    I've searched for it multiple times but the explanation about cyclopropane not being planar is beyond our syllabus and I don't get it...anyways our mark schemes always refer to it not being planar so just remember this

    Now I think that 2 is correct:p The WHOLE curve shifts to the right. Energy above any value is the area under the curve to the right of that value...so if u shade areas of different values of energy, you will find that the area will be higher for the curve of higher temp(shifted to the right...
