Answer:
(d) has an extremely large equilibrium constant.
Explanation:
Hello,
Considering a generic chemical reaction:
The equilibrium constant is defined as:
![K=\frac{[C]^c_{eq}[D]^d_{eq}}{[A]^a_{eq}[B]^b_{eq}} \\](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BC%5D%5Ec_%7Beq%7D%5BD%5D%5Ed_%7Beq%7D%7D%7B%5BA%5D%5Ea_%7Beq%7D%5BB%5D%5Eb_%7Beq%7D%7D%20%5C%5C)
Now, an irreversible chemical reaction is a reaction in which the reagents are converted into products with no chance of coming back, so, considering the previous chemical reaction, the concentration of both A and B tends to be zero, so an extremely large equilibrium constant is gotten.
Best regards.
The balanced chemical reaction for the system given is as follows:
2Mg + 2HCl = 2MgCl + H2
The mole ratio of the reactants is one is to one which means with a given amount of magnesium requires the same amount of hydrochloric acid to have a complete reaction. If supplied exactly, then after the reaction, all of the reactants are consumed and formed into the products.
Answer:
1384 kJ/mol
Explanation:
The heat absorbed by the calorimeter is equal to the heat released due to the combustion of the organic compound. C is the total heat capacity of the calorimeter and Δt is the change in temperature from intial to final:
Q = CΔt = (3576 J°C⁻¹)(30.589°C - 25.000°C) = 19986.264 J
Extra significant figures are kept to avoid round-off errors.
We then calculate the moles of the organic compound:
(0.6654 g)(mol/46.07) = 0.0144432 mol
We then calculate the heat released per mole and convert to the proper units. (The conversion between kJ and J is infinitely precise and is not involved in the consideration of significant figures)
(19986.264 J)(1kJ/1000J) / (0.0144432 mol) = 1384 kJ/mol
A tend line I believe (I am going off the other guy cause they are right.)
