A coil of self-inductance 50 henry is joined to the terminals of a battery of e.m.f. 2 volts through a resistance of 10ohm and a steady current is flowing through the circuit. If the battery is now disconnected, the time in which the current will decay to 1//e of its steady value is

Following are the values of E_(a) and Delta H for three reactions carried out at the same temperature : I: E_(a) =20 kJ mol^(-1), Delta H =-60 kJ mol^(-1) II: E_(a) =10 kJ mol^(-1), Delta H =-20 kJ mol^(-1) III: E_(a) =40 kJ mol^(-1), Delta H=+15 kJ mol^(-1) If all the three reaction have same frequency factor then fastest and slowest reactions are :

Consider two reactions having same Arrhenius factor A, but different energy of activation. (i) A rarr B , Ea_(1)=20kJ (ii) Crarr D, Ea_(2)=30kJ Both are at temperature 25^(@)C It temperature in both reaction is increased slightly in such a way that change in temperature in both case is same than choose the correct options.
