Answer:
D) Rate = K [NO2][Cl2]
Explanation:
2 NO2 + Cl2 → 2 NO2Cl (overall reaction)
NO2 + Cl2 → NO2Cl + Cl (slow)
NO2 + Cl → NO2Cl (fast)
The rate-determining step is the slowest step in a reaction mechanism. Because it is the slowest, it determines the rate of the overall reaction.
Rate of reaction is typically given as;
Rate = K [Reactants]
In the slow step i the reaction mechanism, the reactants are; NO2 and Cl2. Since both are not intermediates, there is no need for further working out.
Rate = K [NO2][Cl2]
The reaction of N2 and H2 to generate NH3 is as follows:N2 + 3H2 ⇒2NH3
Since H2 is in excess amount in this reaction, the determine factor is N2. The ratio of N2 and product NH3 is 1:2. Therefore, 4.08 moles of N2 can generate 4.08*2 = 8.16 mole of NH3.
Grams of NH3 = moles of NH3 * molar mass of NH3 = 8.16 mole * 17 g/mole = 139 g.
139 grams of nh3 can be produced from 4.08 mol of n2 and excess h2.
Answer:
Equation is: 2CH4(g) <----> C2H2(g) + 3H2(g)
Explanation:
In the reaction above;
1.) At equilibrium, the rate of the forward reaction (CH4 decomposing into C2H2 and H2) is equal to the rate of the reverse reaction (C2H2 and H2 reacting to form CH4). This is because it is a reversible reaction.
2.) At equilibrium, the concentrations of all substances are not changing.
3.) At equilibrium, both the forward and reverse reactions are still occurring.
But if the pressure of the system is increased, the equilibrium position will shift to the left according to le Chatelier's principle since there are fewer number of moles of gaseous atoms at the left.
