Answer:
A. the speed at which reactants change to products over a given time
Explanation:
The rate of reaction is a measure of the speed of a chemical reaction. In chemical kinetics, the speed at which the reaction occurs is the reaction rate.
- The measurement of the reaction rate is based on the disappearance of a reactant or appearance of the product with increasing reaction time.
- Rate of reaction depends on the:
- nature of reactants.
- concentration of the reactants or pressure
- temperature
- presence of catalyst
- sunlight
Answer:
Chlorine exists as gaseous state while potassium chloride as a solid
Answer:
it contains non polar covalent bond because both shares 2 equal number of electrons between eachother.

Answer:
for the given reaction is 130.19kJ/mol
Explanation:
To Calculate the
, we use the formula:
![\Delta G_{rxn}=\Delta G_{products}-\Delta G_{reactants}](https://tex.z-dn.net/?f=%5CDelta%20G_%7Brxn%7D%3D%5CDelta%20G_%7Bproducts%7D-%5CDelta%20G_%7Breactants%7D)
For the given chemical reaction:
![CaCO_3(s)\rightarrow CaO(s)+CO_2(g)](https://tex.z-dn.net/?f=CaCO_3%28s%29%5Crightarrow%20CaO%28s%29%2BCO_2%28g%29)
We are given:
![\Delta G_{CaCO_3}=-1128.76kJ/mol\\\Delta G_{CaO}=-604.17kJ/mol\\\Delta G_{CO_2}=-394.4kJ/mol](https://tex.z-dn.net/?f=%5CDelta%20G_%7BCaCO_3%7D%3D-1128.76kJ%2Fmol%5C%5C%5CDelta%20G_%7BCaO%7D%3D-604.17kJ%2Fmol%5C%5C%5CDelta%20G_%7BCO_2%7D%3D-394.4kJ%2Fmol)
Now, to calculate
, we put the values in the above equation:
![\Delta G_{rxn}=(\Delta G_{CaO}+\Delta G_{CO_2})-\Delta G_{CaCO_3}](https://tex.z-dn.net/?f=%5CDelta%20G_%7Brxn%7D%3D%28%5CDelta%20G_%7BCaO%7D%2B%5CDelta%20G_%7BCO_2%7D%29-%5CDelta%20G_%7BCaCO_3%7D)
![\Delta G_{reaction}=(-604.17-394.4)-(-1128.76)kJ/mol\\\Delta G_{reaction}=130.19kJ/mol](https://tex.z-dn.net/?f=%5CDelta%20G_%7Breaction%7D%3D%28-604.17-394.4%29-%28-1128.76%29kJ%2Fmol%5C%5C%5CDelta%20G_%7Breaction%7D%3D130.19kJ%2Fmol)
As, the value of
comes out to be positive, the reaction is said to be non-spontaneous reaction.
I think it would be migration. But I might be wrong.
