For the reaction A --> B, the rate constant, k = 4.23 (L*mol-1*sec-1) at 25C, and the activation energy for this reaction is 34.43 kJ/mol. The same reaction was performed at a different temperature and the new value for the rate constant, k = 2.99 L*mol-1*sec-1 . Determine the temperature (in Kelvin) at which this second reaction was performed.
