Geologic time begins with a very long span called Precambrian Time. Precambrian Time ended about 544 million years ago. Scientis
ts have organized geologic time into chunks. The chunks of time span different lengths. Using the model, organize the basic units of geologic time in order from longest to shortest.

Answer:
41.4 s
Explanation:
Given data
- Rate constant (k): 8.42 × 10⁻² s⁻¹ at 800 °C
- Initial concentration of A ([A]₀): 5.00 M
- Concentration of A at a time t ([A]): 0.153 M
Let's consider the following reaction of first order with respect to A.
2 A ⇒ B
We can find the time that it will take for A to decrease from 5.00 M to 0.153 M using the following expression.
