Four people weigh a standard mass of 10.00 g on the same balance. The set of readings suggest measurements that are neither precise <span>nor accurate is the one with less mass</span>
Answer:
Explanation:
Hello!
In this case, considering the given table, we are able to represent the symbolic rate law as shown below:
Thus, by using the following steps, we can find both m (BF3 order of reaction) and n (BF3 order of reaction):
- Experiment 1 and 2 for the calculation of n:
So we plug in to obtain:
So the order of reaction with respect to NH3 is 1.
- Experiment 3 and 4 for the calculation of m
So we plug in to obtain:
So the order of reaction with respect to BF3 is also 1.
Now, we can compute the rate constant by solving for it on any of the experiments there, say experiment 1:
Thus, the initial reaction rate for the 0.50M BF3 and 0.020M NH3 is:

The answer is B. making sawdust.
Because, to make sawdust you have to shred wood and you can't reverse that. Therefore, making sawdust is irreversible.
