Answer:
The choice of the answer is fourth option that is -61 degrees.
Therefore the temperature drop is -61°Centigrade.
Explanation:
Given:
The temperature in a town started out at 55 degrees
Start temperature = 55°Centigrade. (Initial temperature)
End of the Day = -6°Centigrade. (Final temperature)
To Find:
How far did the temperature drop?
Solution:
We will have,
Substituting the above values in it we get
Therefore the temperature drop is -61°Centigrade.

The speed of sound depends on these two things: The type of medium and the temperature of the medium; option a.
<h3>What is the speed of sound?</h3>
The speed of sound is the distance covered in meters over a given period of time.
Speed = distance/time
The speed of sound depends on the following:
- temperature - the speed of sound increases with temperature
- medium - the speed of sound increases with increase in density of the medium.
In conclusion, the speed of sound increases with temperature.

Answer:-
Option 2
Explanation:-
In a multi step reaction, the overall reaction is as fast as the slowest step only.
So the rate of a multistep reaction is the same as the rate of its slowest step.
The gas phase reaction was found to be second order wrt NO2.
So the slowest step must have 2 NO2 since the dependence is second order on NO2.
It was also found to be zero order wrt CO.
So the slowest step must not contain any CO since it’s presence has no effect on the reaction (zero order).
Among all options, only number 2 meets the two criterion
Thus the steps are
NO2 + NO2 – NO3 + NO (Slow)
NO3 + CO – NO2 + CO2 (Fast)
