Read the following statements carefully.(i) According to a convention, the cell potential of hydrogen electrode (S.H.E.) is considered to be zero at all temperatures.(ii) e.m.f. of the cell Pt(s)/H2(g, 1 bar )/H+ (aq, 1 M) || Zn2+ (aq,1M) / Z n is – 0.76. This negative value indicates that Zn2+ ion reduces less easily then H+ ions.(iii) Copper does not dissolve in HCl but dissolves in HNO3 as in nitric acid it gets oxidised by nitrate ions.(iv) Inert metals like Pt or Au are used in certain electrodes i.e., these metals does not participate in reaction but provide surface for oxidation and reduction reactions. (v) Fluorine has the highest electrode potential thereby making it the strongest oxidising agent whereas lithium with lowest electrode potential is the weakest oxidising and strongest reducing agent.Which of the following are the correct statements above?

Read the passage given below and answer the following questions:The rate of a reaction, which may also be called its velocity or speed, can be defined with relation to the concentration of any of the reacting substances, or to that of any product of the reaction. If the species chosen is a reactant which has a concentration c at time t the rate is - dc/dt, while the rate with reference to a product having a concentration x at time t is dx/dt. Any concentration units may be used for expressing the rate; thus, if moles per liter are employed for concentration and seconds for the time, the units for the rate are moles litre–1sec–1. For gas reactions pressure units are sometimes used in place of concentrations, so that legitimate units for the rate would be (mm. Hg) sec–1 and atm. sec–1 The order of a reaction concerns the dependence of the rate upon the concentrations of reacting substances; thus, if the rate is found experimentally to be proportional to the ath power of the concentration of one of the reactants A, to the both power of the concentration of a second reactant B, and so forth, via., rate = k CAα CAβ the over-all order of the reaction is simply n = α + β + ----- (2) Such a reaction is said to be of the αth order with respect to the substance A, the βth order with respect to B.In the following questions, a statement of Assertion followed by a statement of Reason is given. Choose the correct answer out of the following choices on the basis of the above passage.Assertion: Rate of reaction is a measure of change in concentration of reactant with respect to time.Reason: Rate of reaction is a measure of change in concentration of product with respect to time.
