Chemical Kinetics question

2012 · Q65

NEETChemistryChemical KineticsMultiple correct+4 / −1
Activation energy (Eaaa) and rate constants (k1 and k2) of a chemical reaction at two different temperatures (T1 and T2) are related by
  1. A
    ln⁡k2k1=−EaR(1T1−1T2)\ln {{{k_2}} \over {{k_1}}} = - {{{E_a}} \over R}\left( {{1 \over {{T_1}}} - {1 \over {{T_2}}}} \right)lnk1​k2​​=−REa​​(T1​1​−T2​1​)
  2. B
    ln⁡k2k1=−EaR(1T2−1T1)\ln {{{k_2}} \over {{k_1}}} = - {{{E_a}} \over R}\left( {{1 \over {{T_2}}} - {1 \over {{T_1}}}} \right)lnk1​k2​​=−REa​​(T2​1​−T1​1​)
  3. C
    ln⁡k2k1=−EaR(1T2+1T1)\ln {{{k_2}} \over {{k_1}}} = - {{{E_a}} \over R}\left( {{1 \over {{T_2}}} + {1 \over {{T_1}}}} \right)lnk1​k2​​=−REa​​(T2​1​+T1​1​)
  4. D
    ln⁡k2k1=EaR(1T1−1T2)\ln {{{k_2}} \over {{k_1}}} = {{{E_a}} \over R}\left( {{1 \over {{T_1}}} - {1 \over {{T_2}}}} \right)lnk1​k2​​=REa​​(T1​1​−T2​1​)
