Complete the table below regarding the following reaction: 2NOCI - 2NO+CI, E. = 258 Collision diagram Energy of collision Orientation OK? Energy OK? | Product formation? NOCI NOCI 421 42 mol 1854 NOCI - - NOCI NOCI - --CINO 2134 mod NOCI CINO 3402 mol

Answer 1

The given reaction is 2NOCI - 2NO+ Cl2 We can write the reaction in proper orientation such that the C1 from both molecules of NOC1 reacting are forming bond by collision. N-CI - CIMN - 01—01 +2 NO Hence, the proper orientations are those that have a facing towards the C1 from another molecule. i.e. NOCI ++ CINO Now, it is also given that the activation energy of the reaction is given as Ea= 258 kJ/mol Hence, a reaction must have at least 258 kJ/mol of energy for product formation to happen. Hence, we can fill the table as follows:

Collision Diagram	Energy of Collision	Orientation OK?	Energy OK?	Product formation?
NOCI + NOCI	421 kJ/mol	No	Yes	No
NOCI + NOCI	185 kJ/mol	No	No	No
NOCI + CINO	213 kJ/mol	Yes	No	No
NOCI + CINO	340 kJ/mol	Yes	Yes	Yes

Note that both the energy and orientation need to be proper for product formation to happen i.e. the orientation should be Cl facing Cl and energy of collision must be greater than activation energy.
