Question

Chemical reactions involve the making and breaking of chemical bonds. Since different types of bonds have different bond strengths, the energy of the reacting system changes as the reaction progresses. A graph that shows the change in energy as a function of the progress of the reaction is known as a reaction profile.

According to the theories of chemical reactions, when molecules collide in the correct orientation with a sufficient amount of energy, an activated complex or transition state is formed. The reaction then proceeds and the activated complex decomposes into products.

Part A

Consider the following hypothetical molecular collisions and predict which of the following will form potential products, given the values for the energy of activation, Ea, and enthalpy of the reaction, ΔH, in combination with the molecular orientation.

Check all that apply.

NO Ε, = 0.59 kJ, ΔΗ = -1.28 k]

Part B

The progress of a reaction is determined by various steps involving energy changes with respect to collision theory. Identify the key features of the reaction profile below.

Drag the appropriate labels to their respective targets in the energy profile diagram.

from products, D Activation energy be compensated by enthalpy 2 orientation should be - towards each other. org KJ, AH-1. 28 kJ - It will As orientation to is less form b than the product (s) favourable and a + @ AH 2 +9.56 kJ It won't foam pro duet Neither Eq us a orientation.

Eq = 6,36 kJ, OH = -1.58K5 orientation favours byt Ea is higher then SH So it won't from product END + cas __Eq> 4.58 kJ AH = +5,38 KJ Neither orientation favours, nor Eq Us AH. I so, no product - - Eq = 0 No BH = +1,28 kJ mo dut Ea = 2,48KJ AH2 -5,98 KJ scanned with duet will form Cams Panduit will form as both fanours.
