"Compounds A and B react to give a single product, C. Write the rate law for each of the following cases and determine the units of the rate constant by using the units M for concentration and s for time.

a. The reaction is first order in A and second order in B.
b. The reaction is first order in A and second order overall.
c. The reaction is independent of the concentration of A and second order overall.
d. The reaction is second order in both A and B."

Part a: Units of k is where reaction is first order in A and second order in B

Part b: Units of k is where reaction is first order in A and second order overall.

Part c: Units of k is where reaction is independent of the concentration of A and second order overall.

Part d: Units of k is where reaction reaction is second order in both A and B.

Explanation:

As the reaction is given as

where as the rate is given as

where x is the order wrt A and y is the order wrt B.

Part a:

x=1 and y=2 now the reaction rate equation is given as

Now the units are given as

The units of k is

Part b:

x=1 and o=2

x+y=o

1+y=2

y=2-1

y=1

Now the reaction rate equation is given as

Now the units are given as

The units of k is

Part c:

x=0 and o=2

x+y=o

0+y=2

y=2

y=2

Now the reaction rate equation is given as

Now the units are given as

The units of k is

Part d:

x=2 and y=2

Now the reaction rate equation is given as

Now the units are given as

The units of k is

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
