If the enthalpy change of a reaction is `DeltaH` how will you calculate entropy of surroundings?

If the entropy change of a reaction is DeltaS . How will you calculate entropy of its surroundings ?

The enthalphy change for the reaction, H_2O(s)rarrH_2O_(l) is called enthalpy

If the standard enthalpy of formation of methanol is -238.9 kJ mol^(-1) then entropy change of the surroundings will be.

Write thermochemical equation for complete oxidation of one mole of H_2(g) . Standard enthalpy change of the reaction is -286 kJ. Is the value -286 kJ, enthalpy of formation or enthalpy of combustion or both? Explain.

What is standard enthalpy of reaction give example

For an endothermic reaction,where DeltaH represents the enthalpy of the reaction in kJ mol^(-1) , the minimum value for the energy of activation will be

If the enthalpy of vaporisation of water is 186.5 kJ mol^(-1) , then entropy of its vaporisation will be

Calculate standard enthalpy of reaction

How will you calculate reaction enthalpy from data on bond enthalpies?
