Find the Temperature at Which K_p = 42 $\rarr$ 2HI(g) [Given: at 25°C, for H₂(g)

question 59

Multiple Choice

Find the temperature at which K_p = 42.0 for the reaction H₂(g) + I₂(g) $\rarr$ 2HI(g) . [Given: at 25°C, for H₂(g) , $\Delta$ H°_f = 0, S° = 131.0 J/mol·K; for I₂(g) , $\Delta$ H°_f = 62.26 kJ/mol, S° = 260.6 J/mol·K; for HI(g) , $\Delta$ H°_f = 25.9 kJ/mol, S° = 206.3 J/mol·K; assume that $\Delta$ H° and $\Delta$ S° are independent of temperature.]
