<h2>GREETINGS!</h2><h2>_____________________________________</h2><h3>Answer:</h3>

ITS C_{4}H_{10} AND C_{5}H_{12}

<h2>_____________________________________</h2><h3><u>GENERAL FORMULA OF ALKANE</u></h3><h3>                    C_{n}H_{2n+2}</h3>

Where n is the number of CARBONS

<h2>_____________________________________</h2>

A)

By using the General Formula of Alkanes having 4 carbon atoms is

                        C_{4}H_{2x4+2}

                        C_{4}H_{10}

C)

By using the General Formula of Alkanes having 5 carbon atoms is

                         C_{5}H_{2x5+2}

                         C_{5}H_{12}

<h2>_____________________________________</h2>

IF YOU USE THE SAME FORMULA FOR THE OTHER TWO OPTIONS THE OUTCOME WILL NOT BE AS SAME AS GIVEN IN THE QUESTION SO THOSE TWO ARE CAN NOT BE OUR ANSWER

<h2>_____________________________________</h2><h2>HOPE THIS HELPS!</h2>

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
