Why do you think scientists claim to offer only supporting evidence for a theory and not proof?

Because they're not confident enough to confirm it's indeed true but they will support it for they believe it's correct.

The unsaturated hydrocarbon butadiene (C4H6) dimerizes to 4-vinylcyclohexene (C8H12). When data collected in studies of the kine

UkoKoshka [18]

Answer:

The dimerization of butadiene to 4-vinylcyclohexene folows second order kinetics and its rate law will be given by :

$R=k[C_4H_6]^2$

Explanation:

$2C_4H_6\rightarrow C_8H_{12}$

The rate of the reaction ;

$R=k[C_4H_6]^x$

As given in the question , that graph of time verses $\frac{1}{[C_4H_6]}$ was linear but plots of $[C_4H_6]$ or $\ln[C_4H_6]$ was curved.

Generally:

Graph of time verses $[concentration]$ for zero order reaction is linear with negative slope.

Graph of time verses $\ln [concentration]$ for secon order reaction is linear with negative slope.

Graph of time verses $\frac{1}{[concentration]}$ for secon order reaction is linear with positive slope.

So, the dimerization of butadiene to 4-vinylcyclohexene folows second order kinetics and its rate law will be given by :

$R=k[C_4H_6]^2$

Describe the energetics of covalent and ionic bond formation and breakage?

Luda [366]

Answer:

The strength of a covalent bond is measured by its bond dissociation energy, that is, the amount of energy required to break that particular bond in a mole of molecules. The enthalpy of a reaction can be estimated based on the energy input required to break bonds and the energy released when new bonds are formed.
