1-arr In a study of the decomposition of dinitrogen pentoxide in carbon tetrachloride solution at 30 °C N2O5- →2 NO2 + ½ O2 the concentration of N,O5 was followed as a function of time. It was found that a graph of In[N2O5] versus time in minutes gave a straight line with a slope of -6.31×10* min and a y- intercept of -1.34 . Based on this plot, the reaction O order in N,0g and the rate constant for the reaction is min-1. zero first second

Acetic acid and ethanol react to form ethyl acetate and water, like this: HCH,CO,(aq)+c,H,OH(aq) → C,H,CO,CH;(aq)+H,0(1) Imagine 137. mmol of c,H,CO,CH, are removed from a flask containing a mixture of HCH3CO,, C2H¿OH, C,H,CO,CH; and H,0 at equilibrium, and then answer the following questions. O Zero. What is the rate of the reverse reaction before any C2H5CO2CH3 has been removed from the flask? O Greater than zero, but less than the rate of the forward reaction. Greater than zero, and equal to the rate of the forward reaction. Greater than zero, and greater than the rate of the forward reaction. O Zero. What is the rate of the reverse Greater than zero, but less than the rate of the forward reaction. reaction just after the C2H5CO2CH3 has been removed from the flask? Greater than zero, and equal to the rate of the forward reaction. Greater than zero, and greater than the rate of the forward reaction. Zero. What is the…

The enzyme catalase catalyzes the decomposition of hydrogen peroxide: 2 H2O2 ++ 2 H20 + O2 The turnover number (kea) for catalase is 40,000,000 sec-1.

Nitroglycerine ( C,H,N,O,) is a very strong explosive that degrades over time and is too shock sensitive to transport safely. Dynamite is made by combining nitroglycerine with stabilizers and adsorbents, which makes it much safer to use. The explosion of nitroglycerin can be represented by: 4 C,H,N,O,() → 6 N2(9) + 12 CO(9) + 10 H,0(9) + 7 O2(9) A stick of 40% dynamite is about 20 cm long and about 3 cm in diameter and weighs 241 grams. It is 40.0% nitroglycerine by mass. What is the total number of moles of gas produced when a stick of 4o% dynamite explodes? mol gas

(a) Consider the following data that have been obtained for the decomposition of N2O5(g) at 67 °C according to the reaction: 2 N2O5(g) 4 NO2(g) + O2(g) [N2O5]/mol dm-3 t/s 0 2.000 120 1.41 240 0.994 360 0.698 480 0.492 600 0.346 (i) Based on the above data, briefly describe two methods which can be used to determine the order of the reaction and the rate constant. (i) Use the methods you described above to determine the order of the reaction and the rate constant. (b) The rate constant for the decomposition of a certain substance is 1.70 x 10-2 dm³ mol¹¹ at 24°C and 2.01 x 10-2 dm³ mol-¹s¹ at 37°C. Calculate the activation (Ea) energy of the reaction.
