ApplicationChemical reactionsThe response of carbon, nitrogen and its compounds is important in mitigating environmental pollution and the energy crisis
(1) the method for handling no in the tailings of a nitrate plant is:CatalystWhen present, return no to n2. Known:
Thermal chemical equations for nitrogen and water vapour reaction to generate hydrogen and nitrogen monoxide are
(2) the reaction of the mixture of a mol co and 3a mol h2 to methanol at pressure of 0. 1 mpa is as follows: co(g)+2h2(g) ⇌ch3oh(g)h1 the balanced constant expression of the reaction is
2 if container capacity remains unchanged, the following measures may increase methanol production
A. Higher temperatures
B. Separating ch3ah from the system
C. Filling in he, increasing the overall pressure of the system
(3) the rate of conversion from no to n2 measured by a study team in a laboratory studying the effects of a catalyst is as shown in figure 1
If co is not used, the temperature is above 775°c and the no decomposition rate is found to be lower for possible reasons
N(no)
N (co)
= 1 condition, the optimal temperature should be controlled around
Catalysing nox with cxhy (hydrocarbons) will also eliminate nox contamination
(4) fuel cell units consisting of no2, o2 and melted nano3 as illustrated in figure 2, producing an oxide y in graphite i electrodes during use
