Expert Answer:

Rate of reaction is directly proportional on rate constant.
straight k subscript 1 over straight k subscript 2 equals Ae to the power of negative RT subscript 1 end exponent over Ae to the power of negative RT subscript 2 end exponent
straight k subscript 1 over straight k subscript 2 equals straight e to the power of negative straight T subscript 1 end exponent over straight e to the power of negative straight T subscript 2 end exponent
5 over straight k subscript 2 equals fraction numerator begin display style straight e to the power of negative left parenthesis 273 plus 40 right parenthesis end exponent end style over denominator begin display style straight e to the power of negative left parenthesis 273 plus 80 right parenthesis end exponent end style end fraction

straight k subscript 2 space equals straight e to the power of negative 313 end exponent over straight e to the power of negative 353 end exponent 5
straight k subscript 2 equals 5 straight e to the power of 40

rate space of space reaction space will space become space straight e to the power of 40 space space end exponent space times space of space its space previous space rate.
