For silver, C p ( J K - 1 m o l - 1 ) = 23 + 0.01 T . If the temperature T of 3 moles of silver is raised from 300 K t o 1000 K a t 1 a t m pressure, the value of Δ H will be close to:

Step-by-step solution

Δ H = ∫ T 1 T 2 C p , m d T = 3 × ∫ 300 1000 23 + 0.01   T d T = 3 23 1000 - 300 + 0.01 2 1000 2 - 300 2 = 61950   J ≈ 62   k J .
