The internal energy of a system remains constant when it undergoes (i) a cyclic process (ii) an isothermal process (iii) an adiabatic process (iv) any process in which the heat given out by the system equal to the work done on the system

Products are favored in a chemical reaction taking place at a constant temperature and pressure. Consider the following statements : (i) The change in Gibbs energy for the reaction is negative. (ii) the total change in Gibbs energy for the reaction and the surroundings is negative. (iii) The change in entropy for the reaction is positive. (iv) The total change in entropy for the reaction and the surrounding is positive. The statments which are ALWAYS true are :

Which of the following statemen is /are correct about order of a reaction? I. The order of a reaction can be a fractional number. II. Order of a reaction is experimentally determined quantity. III. The order of a reaction is always equal to the sum of the stoichimetric coefficients of reactants in the balanced chemical equation for a reaction. IV. The order of a reaction is the sum of the powers of molar concentration of the reactants in the rate law expression. Choose the correct option.

Read the following paragraph and answer the questions given below , Stable equilibrium is of various type . Mechanical equilibrium is achieved when all particles are at rest and total potential energy of the system is minimum . At any stage where particles are at rest but the system is not at stabel equilibrium as it can reduce its potential energy by reverting to another position, is called metastable equilibrium . Thermal equilibrium is result from the absence of temperature gradients in the system. chemical equilibrium is obtained when no further reaction occurs between reacting substances, i.e forward and reverse rates of reaction are equal. when steam with solid iron at high temperature Fe_3O_4(s) and hydrogen gas are produced . But the reaction never goes to completion. this is because as the products are formed the reaction proceeds in reverse direction and when rate of reverse reaction is equal to rate of forward reaction , the concentration of reactants and products become constant and equilibrium is reached. Which of the following is correct ?
