False.
More the number of atoms, more will be the bonds and hence more types of arrangeents and more disorder. Thus N2O4 has more disorder (entropy) than NO2

QUESTION 10 Consider the reaction: 2 NO2(g) = N204(8) AG° = -5.40 kl.mol-1 If NO2 = 0.25 atm and N204 = 0.60 atm, what is A G of the system at 25°C? O A. 2.0 x 102J/mol OB.5.6 kJ/mol O C.-5.4 kJ/mol o D.-4.9 kJ/mol
uestion Completion Status: N204(8) <...> 2 NO 2(8) At 25°C, 0.11 mole of N204 reacts to form 0.10 mol of N204 and 0.02 mole of NO 2. At 90'C, 0.11 mole of N204 forms 0.050 moles of N204 and 0.12 mole of NO2. From this data, we can conclude The reaction is exothermic the equilibrium constant for the reaction above increases with an increase in temperature. N204 molecules react faster at 25°C than at 90°C. O None of these are...
5. True/False: For a given transfer of energy, a greater change in entropy occurs when the temperature is high. False, because as temperature decreases there is a greater change in entropy. False, because only heat flow affects the change in entropy, not temperature. True
A proposed mechanism for a reaction is as follows: NO2(g) + NO2(g) + N204(8) Fast/Equilibrium Step N2048) -> NO(g) + NO3(g) Slow NO3(g) NO) + O2(g) Fast The target rate law is rate = k (NO2)2 The target reaction is 2NO2(e) 2NON + O2) A.
