Answer:
c. 131 kPa
Explanation:
Hello!
In this case, since the relationship between volume and pressure is inversely proportional, based on the Boyle's law:
Considering that the standard pressure is 101.325 kPa, we can compute the final pressure as shown below:
Therefore, the answer is c. 131 kPa .
Best regards!!
The given question is incomplete. The complete question is as follows.
Citrate synthase catalyzes the reaction
Oxaloacetate + acetyl-CoA citrate + HS-CoA
The standard free energy change for the reaction is -31.5 kJ*mol^-1
( a) Calculate the equilibrium constant for this reaction a 37degrees C
Explanation:
(a). It is known that
, relation between change in free energy () of a reaction and equilibrium constant (K) is as follows.
where, T = temperature in Kelvin
The given data is as follows.
T = 310 K, (as 1 kJ = 1000 J)
Now, putting the given values into the above formula as follows.
ln K =
=
ln K = 12.22
K = antilog (12.22)
=
Therefore, we can conclude that value of equilibrium constant for the given reaction is .
Answer:
29 mL
Explanation:
<h3>Equation</h3>
The question needs us to find the volume of the liquid. The equation for volume using density and mass is:
Volume = Mass / Density
<h3>Solve</h3>We can substitute the given values for density and mass into the equation:
The answer we obtained (29 mL) is rounded to two significant figures. When multiplying or dividing, the amount of significant figures in the final answer is always the least amount of significant figures in one of the values.
Below are the significant figure rules:
Nonzero digits will always be significant (eg. 54 --> 2 significant figures)
Zeroes at the beginning of a number will never be significant (eg. 0.1 --> 1 significant figure)
Zeroes between two nonzero digits will always be significant (eg. 504 --> 3 significant figures)
Zeroes following a number will always be significant if the number contains a decimal point (eg. 40.0 --> 3 significant figures)
A whole number, not a fraction, that can be negative, positive or zero are integers. They cannot have decimal places.
Now, converting 0.000431 L to decimal an integer as:
Since,
So, .
Hence, the integer value for 0.000431 L is .
Decomposition is a chemical reaction that breaks the reactant into two or more products. Moles of nitrogen gas in the cylinder is 1.63 moles.
The ideal gas equation states the relation of the hypothetical ideal gas according to the pressure, volume, temperature and moles of the gas. It is given by,
Where,
Pressure (P) = 2000 kPa
Volume (V) = 2L
Temperature (T) = 295 K
Gas constant (R)= 0.08206
Substituting values in the equation:
Therefore, 1.63 moles are produced.
