Answer:

The rate law may be determined only by experiment.

Explanation:

For a reaction, A + B ---> C, the rate law can only be determined from experimental data. Chemists determine the rate of reaction by carefully observing the changes in the concentration of species as the reaction progresses.

Hence, the rate law is not determined by inspection of the chemical reaction equation, it must be obtained from the experimental data, hence the answer given.

Which equation agrees with the ideal gas law? mc005-1.jpg mc005-2.jpg mc005-3.jpg mc005-4.jpg
AlexFokin [52]
The ideal gas equation is pV = nRT


From that you can derive several equations, depending on which variables are fixed.


1) When n and T are fixed:

pV = nRT = constant


pV = constant => p1 V1 = p2 V2 => p1 / V2 = p2 / V1 ---> Boyle's Law


2) When n and V are constant:


p / T = nR/V = constant


p / T = constant => p1 / T1 = p2 / T2  ----> Gay - Lussac's Law


3) when n and p are constant


V / T = nR/p = constant   


V / T = constant => V1 / T1 = V2 / T2 ---> Charles' Law


4) When only n is constant


pV / T = nR = constant


pV / T = constant => p1 V1 / T1 = p2 V2 / T2 ----> Combined gas law.



There  you have the four equations that agree with the ideal gas law.

How much energy is required to raise the temperature of a 300.0
Montano1993 [528]

Answer:

Q = 1455.12 Joules.

Explanation:

Given the following data;

Mass = 300 grams

Initial temperature = 22.3

Final temperature = 59.9°C

Specific heat capacity = 0.129 J/gºC.

To find the quantity of energy;

Q = mcdt

Where,

Q represents the heat capacity.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

dt represents the change in temperature.

dt = T2 - T1

dt = 59.9 - 22.3

dt = 37.6°C

Substituting the values into the equation, we have;

Q = 300*0.129*37.6

Q = 1455.12 Joules.
