If a reactions involves only solids, there will no Kc or Kp right?!!
Also what is the color of the flame, when burning an alkane and alkene.

To your first question, you are correct. To your second question, it depends on the alkane used but they burn with orangy colour, which turns into black as the hydrocarbon chain increases

Yes,just calculate.

no my question was which method should I do it according to?
