Find the half life of reaction

The rate of first order reaction is 0.04 mol L^(-1) s^(-1) at 10 min and 0.03 mol L^(-1) s^(-1) at 20 min after initiation. Find the half life of the reaction.

Rate of a reaction A + B rarr Product, is given as a function of different initial concentration of A and B . |{:([A] (mol L^(-1)),(B) (mol L^(-1)),"Initial rate" (mol L^(-1) min^(-1)),),(0.01,0.01,0.005,),(0.02,0.01,0.010,),(0.01,0.02,0.005,):}| Determine the order of the reaction with respect to A and with respect to B . What is the half life of A in the reaction ?

The rate constant of a zero order reaction is 1.5 times 10^–2 mol l^–1 min^–1 at 0.5 M concentration of the reactant. The half life of the reaction is

90% of a first order reaction was completed in 100 min .What is the half life of the reaction ?

For the equilibrium, N_(2)O_(4)hArr2NO_(2) , (G_(N_(2)O_(4))^(@))_(298)=100kJ//mol and (G_(NO_(2))^(@))_(298)=50kJ//mol . ( a ) When 5 mol/litre of each is taken, calculate the value of DeltaG for the reaction at 298 K . ( b ) Find the direction of reaction.
