Answer:  

Explanation:  There are many ways that a researcher can minimize experimental errors in an investigation. The most important ones are described below-

1) First of all,the researcher must be fully aware of the procedure while performing an experiment. So he must go thoroughly with the procedure and prepare all types of chemical already in hand before performing the experiment.

2) The next important thing is that mistakes can only be corrected through repetition of the experiment. Thus one should repeat th experiment twice or thrice by modifying it and before reaching to any conclusion.

A given reaction has an activation energy of 24.52 kj/mol. at 25°c, the half-life is 4 minutes. at what temperature will the hal
igor_vitrenko [27]
According to half life equation:

T(1/2) = ㏑2 / K1

when the T(1/2) = 4 min * 60 = 240 sec

by substitution:

240 = 0.6931 / K1

K1 = 2.9 x 10^-3

when the second T(1/2) = 20 sec, so to get K2:

T(1/2) = 0.6931 / K2

by substitution:

20 = 0.6931 / K2

∴K2 = 3.4 x 10^-2

so, we can get T2 by using this formula:

㏑ (K2/K1) = Ea/R (1/T1 - 1/T2)

by substitution:

㏑(3.4 x 10^-2)/(2.9 x 10^-3) = (24520 / 8.314) (1/298 - 1/T2)

∴ T2 = 396.7 K

         = 396.7 - 273 = 123.7 °C
