Question
In the combustion of meth CH_4(g) + 2 O_2 (g) rightarrow CO_2 (g) + 2 H_2O(g). which reactance lass has the disappearance? CH_4 0_2 CO_2 H_2O CH_4 and O_2 have the same rate of disappearance. For the rate law Rate = K[A][B]^1/2, the partial order with respect A is the period order with to B is and the total order is 0; 1/2; 1/2 1; 1/2 ;1 1;1/2;3/2 1;1/2;5/2 The orders cannot determined without a chemical reaction. If the reaction 3 A + B + 1/2 C rightarrow 2 D + E is first order overall, which of these could be the units of its rate constant, k? 1/s M/s 1/Ms 1/Ms^2 Ms which of the following must be true of an intermediate in a reaction mechanism? is produced by an elementary step is consumed in an elementary step is included in the net reaction for the mechanism I only II only III only I and II only I, II and III A proposed mechanism for the decomposition of ozone in the stratosphere is: Step 1: CI(g) + O_3 (g) rightarrow CLO(g) + O_2(g) Step 2: CIO(g) + O_3, (g) rightarrow CI(g) + 2 O_2(g) What is the molecularity of step 1? Zeromolecular unimolecular bimolecular termolecular More information is needed to answer this question.Explanation / Answer
12) stoichiometry of oxygen is 2 .so it will have greater rate of disappearance. Option (2)
13) wrt A = 1; wrt B = 0.5
Total order = 1+0.5 = 1.5
Option (c)
14)
For first order recation units are time-1
Here we have option (a) sec-1
15)
1 and 2 are correct . It will not be in mechanism
16)
Two molecules participate in reaction . So it is bimolecular
Option (c)
