The rate law for a reaction is rate = k[A]2. What is the overall order of this reaction, and which two varaibles, when graphed,

will give a straight line for this reaction? A. first order, In[A]t versus t B. first order, 1/[A]t versus t C. second order, In[A]t versus t D. second order, 1/[A]t versus t

Answer:

D. second order, 1/[A]t versus t

Explanation:

Since the power of the concentration is 2 in the rate law, it is a second order reaction. Also, for a second order reaction, the variables that would yield a straight line when graphed are 1/[A]t versus t

Answer:

The molecular formula of estradiol is: C_{18}H_{24}O_2.

Explanation:

Molar mass of of estradiol = M= 272.37 g/mol

Let the molecular formula of estradiol be C_xH_yO_z

Percentage of an element in a compound:

\frac{\text{Number of atoms of element}\times \text{Atomic mass of element}}{\text{molecular mass of element}}\times 100

Percentage of carbon in estradiol  :

\frac{x\times 12 g/mol}{272.37 g/mol}\times 100=79.37\%

x = 18.0

Percentage of hydrogen in estradiol  :

\frac{y\times 1g/mol}{272.37 g/mol}\times 100=8.88\%

y = 24.2 ≈ 24

Percentage of oxygen in estradiol  :

\frac{z\times 16 g/mol}{272.37 g/mol}\times 100=11.75\%

z = 2

The molecular formula of estradiol is: C_xH_yO_z:C_{18}H_{24}O_2

Ira Lisetskai [31]

Answer:

The activation energy for an endothermic reaction is quite large and usually takes extra energy from the environment, it is normally not a natural spontaneous process.

Explanation:

  • Endothermic reactions require absorbing energy of the surrounding mainly in the form of heat.
  • Chemical energy needs energy input to break the bonds.
  • Examples of endothermic reactions: Photosynthesis , melting of ice , and evaporating liquid water.
