V1 = 445ml V2 = 499ml
T1 = 274 K T2 = ?
By Charles Law,
V1/T1 = V2/T2
445/274 = 499/T2
By solving we get,
T2 = 307.25 K
An example of an exothermic reaction will be formation of ice

Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
(1) is second order in B and overall third order.
2A + B → C
Order of the reaction = sum of stoichiometric coefficient
= x + 2 = 3
x = 1
Rate of the reaction =R
![R=k[A]^1[B]^2](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5E1%5BB%5D%5E2)
(2) is zero order in A and first order in B.
2A + B → C
Rate of the reaction =R
![R=k[A]^0[B]^1=k[B]^1](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5E0%5BB%5D%5E1%3Dk%5BB%5D%5E1)
Order of the reaction = sum of stoichiometric coefficient
= 0 + 1 = 1
(3) is zero order in both A and B .
2A + B → C
Order of the reaction = sum of stoichiometric coefficient
= 0 + 0 = 0
Rate of the reaction =R
![R=k[A]^0[B]^0=k](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5E0%5BB%5D%5E0%3Dk)
(4) is first order in A and overall zero order.
2A + B → C
Order of the reaction = sum of stoichiometric coefficient
= 1 + x = 0
x = -1
Rate of the reaction = R
![R=k[A]^1[B]^{-1}](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5E1%5BB%5D%5E%7B-1%7D)
Answer:
If this trend continues, the following week will be cooler, and a large amount of rain will fall.
Explanation:
Patterns and trends can often be found in data sets. During the week that Cho recorded the weather, the temperatures consistently dropped by one to four degrees each day. At the end of the week, the amount of precipitation increased daily.
