Endothermic change 5 of 9 if something is lower down on the energy diagram than something else is is said to be... More energetically stable 6 of 9 The minimum energy required for a reaction to occur is known as the... Activation Energy 7 of 9 If the molecules don't, for example, hit each other with enough energy, then nothing happens. We say that the mixture is Kinetically Stable 8 of 9 Q9 continued... even though it may be........................ with respect to its possible products. Energetically Unstable 9 of 9
