Which is a measure of how hot or cold something is?

1 answer:

8 0

By measuring the temperature of a thing it can be determined whether it is hot or cold. Temperature of the thing can be measured by degree Centigrade or by degree Fahrenheit. This is the instrument that will exactly measure the temperature of the substance and whether it is hot or cold. If the substance has a higher temperature than our body temperature then it would automatically feel hot to us and if the temperature of the substance is lower than our body temperature, then it will definitely feel cold to us. This is our sense telling us whether the substance in question is hot or cold.

Answer:

Rate = $k[NO_{2}][F_{2}]$

Explanation:

Two reactants are present in this reaction which are $NO_{2}and F_{2}$
We know overall order of a reaction is summation of individual order with respect to reactants present in rate law equation.
Here, overall order of reaction is 2 including first order with respect to $F_{2}$
So, rate of reaction should also be first order with respect to another reactant i.e. first order with respect to $NO_{2}$
So, rate law: rate = $k[NO_{2}][F_{2}]$
