Solve this: Q.4. Consider the reaction 4 N O 2 ( g ) + O 2 ( g ) → 2 N 2 O 5 ( g ) , ∆ r H = - 111 k J . If N 2 O 5 (s) is formed instead of N 2 O 5 (g) in the above reaction, the ∆ r H value will be (Given, ∆ H of sublimation for N 2 O 5 is 54 kJ m o l - 1 ) (a) - 165 kJ (b) + 54 kJ (c) + 219 kJ (d) - 219 kJ Share with your friends Share 16 Akansha Chauhan answered this Dear Student, Please find below the solution: -67 View Full Answer
