Question

A mixture of 1.00 mol SO2(g), 2.00 mol O2(g) and 1.00 mol SO3(g) is placed in a 1.00 dm3 container and allowed to reach equilibrium.2SO2(g) + O2(g) 2SO3(g). Identify two features of colliding molecules that react together in the gas phase.

Answer 1

molecules have sufficient / minimum energy / activation energy

 Corresponding geometry / correct orientation
