Two main rules on how you form a rate equation from mechanisms of a reaction? |
1.) Only species in the rate determining step are included in the rate equation 2.) Orders of reaction for each species indicate their molar ratios in the rate determining step |

What is enthalpy change of atomisation? Atomisation of Iodine? |
The energy taken in (ALWAYS POSITIVE) by a species to form one mole of gaseous atoms from an element in its STANDARD STATE. 1/2 I (s) -> 2 I (g) Here, Iodine's standard state is a solid, and a single atom is used to represent the giant molecular covalent structure (I2 would be a gas as it's diatomic) |
What state change is involved? |
