K p has the value of 10-6 atm 3 and 10-4 atm 3 at 298 K and 323 K respectively for the reaction CuSO 4 ⋅ 3 H 2 O ( s ) leftharpoons CuSO 4( s )+3 H 2 O ( g ) Δ r H ° for the reaction is: (A) 7.7 kJ/mol (B) -147.41 kJ/mol (C) 147.41 kJ/mol (D) None of these

Tardigrade Admin · Accepted Answer

In ( K P 2/ K p 1)=(Δ H °/ R )[(1/ T 1)-(1/ T 2)] = In ((10-4/10-6))=(Δ H °/8.314)[(25/298 × 323)] Δ r H °=147.41 kJ / mol

Q. $K_{p}$ has the value of $1 0^{- 6} a t m^{3}$ and $1 0^{- 4} a t m^{3}$ at $298 K$ and $323 K$ respectively for the reaction
$C u S O_{4} \cdot 3 H_{2} O (s) ⇌ C u S O_{4} (s) + 3 H_{2} O (g)$
$Δ_{r} H^{\circ}$ for the reaction is:

7.7 kJ/mol

-147.41 kJ/mol

147.41 kJ/mol

None of these

In $\frac{K _{P_{2}}}{K _{p_{1}}} = \frac{Δ H ^{\circ}}{R} [\frac{1}{T _{1}} - \frac{1}{T _{2}}]$
= In $(\frac{1 0 ^{- 4}}{1 0 ^{- 6}}) = \frac{Δ H ^{\circ}}{8.314} [\frac{25}{298 \times 323}]$
$Δ_{r} H^{\circ} = 147.41 k J / m o l$
