Radius ratio for NaCl is 0.525, for KBr is 0.60 and for KCl is 0.65. Find radius ratio for NaBr.

Options

A. 0.485
B. 0.585
C. 0.378
D. 0.454

Explanation

To find the radius ratio for NaBr, we can use the given radius ratios for NaCl, KBr, and KCl. The radius ratio is defined as the ratio of the radius of the cation to the radius of the anion.

### Step-by-Step Solution:

1. **Understand the Radius Ratio**:
The radius ratio (r) is defined as:
\[
r = \frac{r_{cation}}{r_{anion}}
