A first order reaction has a half - life period of 69 .3 sec at 0.10 "Mol litre "^(-1) reactant concentration then the rate constant will be

6. ^(*) The current in a metal wire of cross-sectional area 10^(-6)m^(2) is 1.6A .If the free electron density of the metal is 8times 10^(28)m^(-3) then the drift speed of electrons is (A) 1.25times10^(-3)ms^(-1) (B) 2times10^(-3)ms^(-1) (C) 1.25times10^(-4)ms^(-1) (D) 2times10^(-4)ms^(-1)

6. ^(*) The current in a metal wire of cross-sectional area 10^(-6)m^(2) is 1.6A .If the free electron density of the metal is 8times x^(2) x 10^(28)m^(-3) then the drift speed of electrons is (A) 1.25times10^(-3)ms^(-1) (B) 2times10^(-3)ms^(-1) (C) 1.25times10^(-4)ms^(-1) (D) 2times10^(-4)ms^(-1)

The first order reaction has a specific rate 10^(-3) s^(-1) How much time will it take for 10 g of the reactant to reduce to 5 g ?

The rate of first-order reaction is 1.5 xx 10^(-2) M "min"^(-1) at 0.5 M concentration of reactant. The half-life of reaction is

A to B is a first order reaction with rate 6.6 xx 10^(-5) m-s^(-1) . When [A] is 0.6 m, rate constant of the reaction is……..
