Chapter 14, question 82.
00:03
We have a conceptual question.
00:05
If you were going to build a system to check the effectiveness of automobile catalytic converters on cars, what substances would you want to look for in the car exhaust? so there is an important thing about this catalyst.
00:19
The catalyst must be effective over a wide range of operating temperatures.
00:24
So it has to be effective in cold and very hot temperature.
00:30
They must continue to be active despite the fact that various components of the exhaust can block the active size of the catalysts.
00:39
So what this means is let's say this is a catalyst and there's a flow of gas and exhaust components and everything.
00:48
And let's say it is blocking this area.
00:52
So whatever we're going to have the molecule to react on the catalytic surface, this is a little.
01:00
Is not going to work since this is blocked.
01:04
So that's also very important.
01:06
And the catalyst must sufficiently rug to withstand exhaust gas turbulence and the mechanical shocks of driving under various conditions for thousands of miles.
01:17
So this basically needs to be stable.
01:21
A part b, automobile catalytic converters have to work at high temperatures as hot exhaust gas stream through them...
