69. Solving a chemistry problem

1. Decomposition of sodium perborate NaBO3 + H2O → NaH2BO3 + 1/2O2 first order reaction.
The reaction rate constants at Т1=303.2 K and Т2=308.2 K are 2.2•10-3 and 4.1•10-3 min-1, respectively. Calculate the activation energy of the reaction and the time during which 99.99% sodium perborate will decompose at T3=313.2 K.
