Consider the equation:
CHCl3(g)+Cl2(g) > CCl4(g)+HCl(g)
The initial rate of the reaction is measured at several different concentrations of the reactants with the following results: [CHCl3](M) [Cl2](M) Initial rate (M/s)
0.010 0.010 0.0035
0.020 0.010 0.0069
0.020 0.020 0.0098
0.040 0.040 0.027
1. From the data, choose the correct rate law for the reaction.
Rate = k[CHCl3][Cl2]^2Rate = k[CHCl3]^2[Cl2]^1/2Rate = k[CHCl3][Cl2]Rate = k[CHCl3][Cl2]^1/2
2. the rate constant (k) for the reaction. Express your answer using three significant figures.

1.

2. The rate constant (k) for the reaction is

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

k= rate constant

x = order with respect to

y = order with respect to

n = x+y= Total order

1. a) From trial 1:  (1)

From trial 2:   (2)

Dividing 2 by 1 :

therefore x=1.

b)  From trial 2:   (3)

From trial 3:   (4)

Dividing 4 by 3:

therefore

2. to find rate constant using trial 1:

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
