Explanation:
D.) It depends cuz no yeild is 100%..I mean side reactions also occur in most of the reactions. So mass of the reactant is not equal to the mass of the product. Hope it helps
Answer
A. It changes the rate, R
Explanation
When we change the concentration of the reactants in a chemical reaction, it affects the rate of reaction that happens in the process. Typically, the rate of reaction will decrease with time if the concentration of the reactants decreases because the reactants will be converted to products. Similarly, the rate of reaction will increase when the concentration of reactants are increased.
Answer:

Explanation:
Hello,
In this case, it is widely known that for isochoric processes, the change in the enthalpy is computed by:

Whereas the change in the internal energy is computed by:
So we compute the initial and final temperatures for one mole of the ideal gas:

Next, the change in the internal energy, since the volume-constant specific heat could be assumed as ³/₂R:

Then, the volume-pressure product in Joules:

Finally, the change in the enthalpy for the process:
