1➤ Write the expressions for rates of reaction for : 2N₂O(g) 4NO2(g) + O₂(g)?
=> Ans Answer Not Available
2➤ Q. 41. What are the units of rate constant of a first order reaction?
=> Ans. The units of rate constant (k) for the first order reaction is per time (or s ¹).
3➤ Q. 42. What do you mean by a complex reaction?
=> Ans. Complex reaction: A reaction which follows a simple rate law but takes place in a series of steps or elementary reactions is called a complex reaction.
4➤ Identify the molecularity and write the rate law for the following elementary reaction : NO()+OR) NO(g) +0(g)
=> Ans. For the reaction, NO+ONO-O Molecularity is 2. Rate law: Rate=k[NO] x [0₂]
5➤ Give two examples of a first order reaction.
=> Ans. The examples of first order reaction are: (1) Decomposition of H₂O₂: 2H,02H₂O) +0g) Ratek[H₂O₂] (2) Decomposition of N₂O, : 2N₂O4NO2+0 Rate=k[N,O,1
