Define standard electrode potential.

the values of standard temperature and pressure is :

Give the appropriate reason for the followings: a. It is a preferable to determine a change in enthalpy than change in internal energy. b. It is necessary to define the 'standard state. c. It is necessary to specify the phases of the reactant and products in a thermochemical equation.

The reference standard used for defining atomic mass is

Express the numbers appearing in the following statements in the standard form: The distance between the earth and the moon is 384,000,000 metres. Diameter of the earth is 1, 27 , 56 , 000 metres. Diameter of the sun is 1,400,000,000 metres. The universe is estimated to be about 12,000,000,000 years old.

Define the term standard free energy change (Delta G^(@)) . How is it related to the equilibrium constant K?

The word 'standard' in standard molar enthalpy change implies

Write the equation showing the relationship between standard free energy and standard cell potential.

Let s be the standard deviation of n observations. Each of the n observations is multiplied by a constant c. Then the standard deviation of the resulting number is

The standard absolute entropy of a substance, (S^(Theta)) is the entropy of the substance in its standard state at 1 atm, temperature being
