3. Ea = 306.5 kJ/mol
Thus, According to Arrhenius Equation,
ln(k2/k1) = (306500/8.314)*(1/283 - 1/303)
So, k2/k1 = 5423.378
Hence, the Reaction will be 5423.378 times Faster, at 30°C.
4. For the Reaction, ∆H = 306.5 -107 = 199.5 kJ/mol
∆S = 48.9 J/mol-K
Hence, ∆G = 199500 - (298*48.9) = +184.928 kJ/mol
Thus, the Process isn't expected to occur to a large extent, at 25°C, Since ∆G for this process is positive.

NUMBER 3 AND 4 PLEASE! I JUST NEED #3 AND 4
Ozone Formation: NO2(g), is formed by chemical reactions involving N2(g) and O2(g) at the high temperatures Inside internal combustion engines in our cars. In the presence of sunlight, NO2(g) reacts with O2(g) to generate Os(s) as described by the following overall reaction: NO2(g) + O2(g) = NO(g) + O2(g) E = 306.5 l/mol This chemical process occurs in two steps, as illustrated in the potential energy diagram. In the...

Please answer #3 and #4

Photochemical Smog Photochemical smog is a type of air pollution produced when sunlight acts upon motor vehicle exhaust gases, such as nitrogen oxides (e.g., NO, NO:) to form harmful substances such as ozone (0). These substances participate in a reaction cycle that determines the concentration of pollutants at different times during the day. Ozone Formation: NO:(), is formed by chemical reactions involving N2(g) and O-() at the high temperatures inside internal combustion engines in...

To understand how elementary steps make up a mechanism and how the rate law for an elementary step can be determined. Very often, a reaction does not tell us the whole story. For instance, the reaction NO2(g)+CO(g)→NO(g)+CO2(g)NO2(g)+CO(g)→NO(g)+CO2(g) does not involve a collision between an NO2NO2 molecule and a COCO molecule. Based on experimental data at moderate temperatures, this reaction is thought to occur in the following two steps: NO2(g)+NO2(g)→NO3(g)+NO(g)NO2(g)+NO2(g)→NO3(g)+NO(g) NO3(g)+CO(g)→CO2(g)+NO2(g)NO3(g)+CO(g)→CO2(g)+NO2(g) Each individual step is called an elementary step. Together, these...
