B is the answer I believe so
Answer:
Explanation:
Using the expression shown below as:
Where,
is the number of vacancies
N is the number of defective sites
k is Boltzmann's constant = 
is the activation energy
T is the temperature
Given that:
N = 10 moles
1 mole = 
So,
N = 
Temperature = 425°C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T = (425 + 273.15) K = 698.15 K
T = 698.15 K
Applying the values as:
![ln[\frac {2.3}{6.023}\times 10^{-11}]=-\frac {Q_v}{1.38\times 10^{-23}\times 698.15}](https://tex.z-dn.net/?f=ln%5B%5Cfrac%20%7B2.3%7D%7B6.023%7D%5Ctimes%2010%5E%7B-11%7D%5D%3D-%5Cfrac%20%7BQ_v%7D%7B1.38%5Ctimes%2010%5E%7B-23%7D%5Ctimes%20698.15%7D)
The statement which best characterizes the relationship between a general contractor and a construction manager is that; A construction manager subcontracts a general contractor to perform <em>work</em>.
A construction project manager is saddled with the responsibility of overseeing the planning and delivery of construction projects.
- In essence, they ensure that work is completed on time and within budget. Other functions include organising logistics, delegation of work and tracking of spending.
A general contractor otherwise known as the prime contractor is responsible for the day-to-day oversight of a construction site,<em> employment of labour, management of vendors and trades, and most importantly, the communication of information to all involved parties throughout the course of a building project.</em>
- <em>Ultimately</em><em>,</em><em> </em><em>the </em><em>relationship</em><em> </em><em>between</em><em> </em><em>a </em><em>general contractor and a construction manager is that; A construction manager subcontracts a general contractor to perform work.</em>
