Explanation:
<u>Answer:</u> The atomic radius of iron is 128 pm.
<u>Explanation:</u>
To calculate the radius of the metal having FCC crystal lattice, the relationship between edge length and radius follows:
Where,
a = edge length = 362 pm
r = atomic radius of iron = ?
Plugging values in above equation, we get:
Hence, the atomic radius of iron is 128 pm.
Answer:
-k slope
The term No is the y intercept(does not mean NO) y-intercept
Explanation:
For a straight line graph, the normal equation could be written as
y = mx + c
Where m is the slope and c is the y intercept.
Writing the equation is the form of y = mx + c gives the following;
lnN = -kt + No
As obtained from the question, t is plotted in the x-axis, while lnN is the plot on the y-axis.
Now, we are asked to obtain the slope and the y-intercept. It can be seen that the slope is the coefficient of the term x in this case t. Hence, our slope is -k.
The y-intercept is the other term which in this case is No
