Q1: As per Kirchoff s equation, the heat of reaction is affected by the

ANS:C - temperature

According to Kirchhoff's equation, the heat of reaction is affected by temperature. Kirchhoff's equation describes how the heat of reaction varies with temperature. It states that the change in enthalpy of a reaction at one temperature can be related to the change in enthalpy at another temperature by considering the heat capacities of the reactants and products. In other words, Kirchhoff's equation allows us to calculate the change in enthalpy (Δ𝐻ΔH) of a reaction at one temperature if the change in enthalpy at another temperature is known, provided the heat capacities of the reactants and products are known. The heat of reaction itself (ΔH) is a thermodynamic property that represents the heat released or absorbed during a chemical reaction at constant pressure and is dependent on the temperature at which the reaction occurs. Therefore, temperature is the parameter affected by Kirchhoff's equation
