What else can I help you with?
True or False A large positive value of entropy tends to favor products of a chemical reaction?
True, a large positive value of entropy tends to favor products of a chemical reaction. However, entropy can be offset by enthalpy; a large positive value of enthalpy tends to favor the reactants of a chemical reaction. The true measure to determine which side of a chemical reaction is favored is the change in Gibbs' free energy, which accounts for both entropy and enthalpy, as calculated by: Change in Gibbs = Change in Enthalpy - Temp in Kelvin * Change in Entropy A negative value of Gibbs free energy will always favour the products of a chemical reaction.
True or false The molar enthalpy values and fusion stay the same if you were to reverse the process?
True. The molar enthalpy values for fusion (also known as the enthalpy of fusion) are independent of the direction of the process. This means that the enthalpy change for melting a substance is equal in magnitude, but opposite in sign, to the enthalpy change for freezing the substance.
Do the compounds remain the same as before the reaction when a chemical reaction occurs?
true
What is an antonym of chemical reaction?
I suppose that "chemical reaction" hasn't not a true antonym.
Is it true that reactants of a catalyst assisted reaction are known as substrates?
Yes. it is true.
What is true of the enthalpy reaction?
The enthalpy of a reaction is a measure of the heat energy exchanged with the surroundings at constant pressure. A negative enthalpy change indicates an exothermic reaction, where heat is released. A positive enthalpy change indicates an endothermic reaction, where heat is absorbed.
Which is true of the enthalpy of a reaction?
Its value does not depend on which reactions are added.
What is true of the enthalpy value of an intermediate reaction?
It is multiplied by 2 if the intermediate reaction is multiplied by 2

Which of the following is true for the gas phase reaction shown below 2c2h2 g plus 5o2 g 4co2 g plus 2h2o g Δh equals -2511 kj?
The given reaction is the combustion of acetylene (C2H2) in oxygen (O2) to form carbon dioxide (CO2) and water (H2O). The negative enthalpy change (-2511 kJ) indicates that the reaction is exothermic, meaning it releases heat energy to the surroundings. This reaction is highly favorable in the gas phase due to the large negative enthalpy change.
What is true about the numerical value of the Gibbs free-energy change for a spontaneous reaction?
For a spontaneous reaction, the numerical value of the Gibbs free-energy change (ΔG) is negative, indicating that the reaction is energetically favorable and will proceed in the forward direction. This negative ΔG means that the system is releasing energy and increasing in entropy during the reaction.
Which of the following is true for the gas phase reaction shown below 2c2ho g 5o2 g 4co2 g 2h2o g Δh 2511 kj?
ΔS is positive and G is negative at all temp.Which of the following is true for the gas phase reaction shown below? 2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(g), ΔH = -2511 kJΔS is negative and ΔG is negative at low temperatures.
Which of the following is true for the gas phase reaction shown below 4nh3g plus 5o2g 4nog plus 6h2og Δh equals -0.905 kj?
The reaction is exothermic because the enthalpy change (ΔH) is negative (-0.905 kJ). This means heat is released during the reaction. The reaction forms nitrogen monoxide (NO) and water (H2O) from ammonia (NH3) and oxygen (O2) in the gas phase.
What is the activation energy of peroxodisulphate and iodide reaction?
From an experiment I did in my chemistry lab, I got a value of 52.0 kJ. But I have no idea what the "true" Ea is.
What is the difference between true value and experimental value?
true value is something that is true and experimental value is some thing that has been experimental with
