The rate of a hypothetical reaction involving L and M is found to double when the concentration of L is doubled and to increase
Semmy [17]

Answer: Rate=k[L]^1[M]^2

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.

L+M\rightarrow products

Rate=k[L]^x[M]^y  (1)

k= rate constant

x = order with respect to L

y = order with respect to M

n =( x+y)= Total order

a)  If [L] is doubled, the reaction rate will increase by a factor of 2:

2\times Rate=k[2L]^x[M]^y   (2)

b)  If [M] is doubled, the reaction rate will increase by a factor of 4:

4\times Rate=k[L]^x[2M]^y   (3)

Dividing 2 by 1:

\frac{2\times Rate}{Rate}=\frac{k[2L]^x[M]^y}{k[L]^x[M]^y}

2=2^x

x=1

Dividing 3 by 1

\frac{4\times Rate}{Rate}=\frac{k[L]^x[2M]^y}{k[L]^x[M]^y}

4=2^y

2^2=2^y

y=2

Thus rate law is: k[L]^1[M]^2

given that the mean relating atomic mass of chlorine gas is 35.5 and contains a mixture of two isotopes of mass number 35 and 37
bezimeni [28]

The abundance of isotope 35 = 75%

The abundance of isotope 37 = 25%

Ratio isotope 35 :  isotope 37 = 3 : 1

<h3>Further explanation</h3>

Given

Ar Cl = 35.5

Two isotopes of mass number 35 and 37

Required

The ratio of each isotope

Solution

If the abundance of isotope 35 is x%, then the abundance of isotope 37 is (100-x)%

35.5 = x%.35 + (100-x)%.37

35.5 = 0.35x+0.37(100-x)

35.5=0.35x-0.37x+37

0.02x=1.5

x=75
