What is the standard enthalpy of reaction?

Options

  1. AThe enthalpy change for a reaction under non-standard conditions
  2. BThe enthalpy change for a reaction when all substances are in their standard states
  3. CThe enthalpy change for a reaction carried out at high pressure
  4. DThe enthalpy change for a reaction at any given temperature

Correct answer

B. The enthalpy change for a reaction when all substances are in their standard states

Step-by-step solution

The standard enthalpy of reaction is the enthalpy change for a reaction when all the participating substances are in their standard states.
