Experimental data for a reaction are collected and graphed. What can you conclude about the reaction based on the graph?
A. The reaction is zero order, and the rate constant is the negative of
the slope of the line
B. The reaction is zero order, and the rate constant is the slope of the
line
C. The reaction is first order, and the rate constant is the slope of the
line,
D. The reaction is first order, and the rate constant is the negative eg

1.33 Å

Explanation:

Given that the edge length , a of the KCl which forms the FCC lattice = 6.28 Å

Also,

For the FCC lattice in which the anion-cation contact along the cell edge , the ratio of the radius of the cation to that of anion is 0.731.

Thus,

.................1

Also, the sum of the radius of the cation and the anion in FCC is equal to half of the edge length.

Thus,

 ...................2

Given that:

To find,

Using 1 and 2 , we get:

Size of the potassium ion = 1.33 Å
