Question

We know that the relationship between $K_{c}$ and $K_{p}$is

$K_{p} = K_{c}(RT)^{\Delta n}$

What would be the value of $\Delta n$for the reaction:

$NH_{4}Cl_{(s)}$ $NH_{3(g)} + HCl_{(g)}$?

• A. 1
• B. $0.5$
• C. $1.5$
• D. 2

Answer 1

Answer: (D)

2

Answer 2

: For the reaction:

$NH_{4}Cl_{(s)}$ $NH_{3(g)} + HCl_{(g)}$

$\Delta n = n_{gaseousproducts} - n_{gaseousreac\tan ts}$

$= 2 - 0 = 2$
