Explanation of Solution
The standard Gibbs free energy of reaction
Given:
Refer to the appendix L for the value of standard Gibbs free energy of formation
The chemical reaction of barium with hydrogen chloride is written as,
The value of standard Gibbs free energy of formation
The value of standard Gibbs free energy of formation
Substitute these values in equation (2) to calculate the value of standard Gibbs free energy of reaction
Therefore, the value of standard Gibbs free energy of reaction
Hence, the negative value of standard Gibbs free energy of reaction indicates that the barium metal gives a product-favoured reaction with
The chemical reaction of lead with hydrogen chloride is written as,
The value of standard Gibbs free energy of formation
The value of standard Gibbs free energy of formation
Substitute these values in equation (2) to calculate the value of standard Gibbs free energy of reaction
Therefore, the value of standard Gibbs free energy of reaction
Hence, the negative value of standard Gibbs free energy of reaction indicates that the lead metal gives a product-favoured reaction with
The chemical reaction of mercury with hydrogen chloride is written as,
The value of standard Gibbs free energy of formation
The value of standard Gibbs free energy of formation
Substitute these values in equation (2) to calculate the value of standard Gibbs free energy of reaction
Therefore, the value of standard Gibbs free energy of reaction
Hence, the positive value of standard Gibbs free energy of reaction indicates that the mercury metal does not form a product-favored reaction with
The chemical reaction of titanium with hydrogen chloride is written as,
The value of standard Gibbs free energy of formation
The value of standard Gibbs free energy of formation
Substitute these values in equation (2) to calculate the value of standard Gibbs free energy of reaction
Therefore, the value of standard Gibbs free energy of reaction
Hence, the negative value of standard Gibbs free energy of reaction indicates that the titanium metal gives a product-favoured reaction with
Therefore, the metals
