Data:
Explanation:
The rate constant as a function of the temperature can be expressed using the Arrhenius equation, as follows,
Then, find a value for the constant A, according to the data given in the exercise,
As the rate constant has units then, the reaction corresponds to one of first order. Then, the reaction corresponds to:
Which tell the amount of mass (mol) is produced by second per unity of volume.
Answer:
If the reaction goes twice fast, the reaction rate corresponds to,
The expression above can be reduced to:
Replacing k(T) in order to obtain the temperature T,
Replacing all values,

Answer:
The answer to your question is: Volume = 1.074 x 10⁻⁶ m³
Explanation:
Data
Salt crystal measures 5.44 x 10⁻² m ; 2.5 x 10⁻³ m; 7.9 x 10⁻³ m
From the information I suppose it is a cube, then,
Volume of a cube = length x width x height
Volume = 5.44 x 10⁻² m x 2.5 x 10⁻³ m x 7.9 x 10⁻³ m
Volume = 0.000001074 m³
Volume = 1.074 x 10⁻⁶ m³
Answer:
5.17 x 10^14Hz
Explanation:
V = 3 x 10^8m/s
λ = 580nm = 580 x 10^-9m
f =?
f = V / λ = 3 x 10^8 / 580 x 10^-9
f = 5.17 x 10^14Hz
