What is the accepted value for the heat of solution NH4Cl?
The accepted value for the heat of solution of NH4Cl (ammonium chloride) is approximately +14.8 kJ/mol. This value represents the energy released or absorbed when one mole of NH4Cl dissolves in water at standard conditions.
What is heat of reaction of Diphosphorus Pentasulfide?
If you wanted to, you could ask what the heat of formation is of a given compound such as diphosphorus pentasulfide, but if you want to know about a heat of reaction, you have to specify a reaction. A compound is not a reaction.
What can be said about a reaction with H 620 kJmol and S -0.46 kJ(molK)?
it can never be spontanious
At which temperature would a reaction with AH = -92 kJ/mol, AS = -0.199kJ/(mol·K) be spontaneous?
the answer is 400
How much CaCO3 could be decomposed by 90 000 kj of heat energy?
The molar heat of decomposition for CaCO3 is 179.5 kJ/mol. To find out how much CaCO3 can be decomposed by 90,000 kJ of heat energy, you divide the given energy by the molar heat of decomposition and multiply by the molar mass of CaCO3 (100.1 g/mol). This gives you approximately 50.1 g of CaCO3 that can be decomposed by 90,000 kJ of heat energy.
If you need to reverse the following reaction and multiply it by 2 in order for it to be an intermediate reaction in a Hess's law problem what would be the final value for the enthalpy of reaction yo?
2820 kJ
What would be the final value for the enthalpy of reaction you use for this intermediate reaction?
Can you please provide me with the specific reaction or context for which you need the enthalpy value?
If you need to reverse the following reaction in order for it to be an intermediate reaction in a Hess's law problem what would be the final value for the enthalpy of rea?
286 kJ
If you need to reverse the following reaction and multiply it by 2 in order for it to be an intermediate reaction in a Hess's law problem what would be the final value for the enthalpy of reaction you?
The final value for the enthalpy of reaction would be double the original value. This is because when a reaction is reversed, the sign of the enthalpy value changes (positive becomes negative and vice versa). Multiplying by 2 simply scales this new value.
What is the activation energy of peroxodisulphate and iodide reaction?
The activation energy of the peroxodisulphate and iodide reaction is approximately 75 kJ/mol. This reaction is commonly used in clock reactions to demonstrate the concept of reaction kinetics.

What is the heat of reaction of methane in steam reforming?
The heat of reaction for methane steam reforming is an endothermic process, meaning heat is required for the reaction to occur. The reaction produces hydrogen and carbon monoxide from methane and steam. The heat of reaction for this process is around 206 kJ/mol of methane converted.
If you need to reverse the following reaction in order for it to be an intermediate reaction in a Hess's law problem what would be the final value for the enthalpy of reaction you use for this in?
The final value for the enthalpy of the reverse reaction used in a Hess's law problem would simply be the negative of the original value of the enthalpy of the forward reaction. This is because reversing a reaction changes the sign of the enthalpy change.
Enthalpy of a reaction is -394 kJ mol How would you describe the reaction?
The reaction is exothermic since the enthalpy change is negative (-394 kJ/mol), indicating that it releases energy to the surroundings.

What is true for the gas phase reaction shown below 2NH3 gives n2 plus 3h2 delta H equals 160.58 kj?
The reaction is the decomposition of ammonia gas into nitrogen gas and hydrogen gas. The reaction is endothermic, as indicated by the positive value of ΔH (160.58 kJ). This means that heat is absorbed from the surroundings for the reaction to occur.
What is the heat of formation of NaCl?
The standard enthalpy of formation for sodium chloride is -411,12 kJ/mol.
