Ajet plane is speeding down the runway during takeoff. air resistance is not negligible. identify the forces on the jet.

The activation energy for the reaction no2(g)+co2(g)⟶no(g)+co(g) is ea = 300 kj/mol and the change in enthalpy for the reaction is δh = -100 kj/mol . what is the activation energy for the reverse reaction?

Is this correct if not can u correct me
