Answer:
- <em>0.138 kcal</em>
Explanation:
The answer choices are:
- a) 5.78 × 10⁵ kJ
- b) 138 kcal
- c)0.138 kcal
- d)1.38 × 10⁵ kcal
You must use the conversion factors to convert J to kcal.
- 1cal = 4.184J
Dividing both sides by 4.184J:
⇒ 1 = 1cal/4.184J
- 1kcal = 1,000cal
Dividing both sides by 1,000 cal
⇒ 1 = 1kcal / 1,000 cal
Mutiply<em> 578J</em> by the conversion factors to find <em>kcal</em>:
Notice how the units J and cal cancel to yield kcal at the end.
Answer:
A. c. Keq=[H2]^2[S2]/[H2S]^2
B. b. Keq=[COCl2]/[CO][Cl2]
Explanation:
Hello,
In this case, considering the law of mass action which states that the equilibrium expression is written in terms of the concentration of products divided by the concentration of reactants considering the stoichiometric coefficients as powers we obtain:
A. For the reaction:
The equilibrium expression is:
Therefore, answer is c. Keq=[H2]^2[S2]/[H2S]^2.
B. For the reaction:
The equilibrium expression is:
Therefore, answer is b. Keq=[COCl2]/[CO][Cl2].
Regards.
