Which of the following collisions will initiate the reaction? The energy of the collision is written in kJ beside the possible orientation of the molecules.

The teacher is mostly talking about the distillation of a mixture

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts

Depends on the speed of the car.
