Kenetics

Question 1

Explain why the catalyst is more effective when coated on a unreactive honeycomb

Answer 1

Increased the surface area, so this allows more successful collisions 

Question 2

State how the area under the molecular energy distribution curve changes as a catalyst is introduced without changing the temperature or the total number of molecules

Answer 2

Stays the same ( as the area under the graph is constant)

Question 3

Explain why the slope/gradient of curve R decreases as the time increases


Answer 3

Reactant gets used up

Question 4

Explain in terms of behaviour particles why a high operating pressure is used in the industry

Answer 4

high pressure means more particales in a given volume
which increase the the successful collisions, and produces a small yield faster
