Question

Two reactions A rightwards arrow Products and B rightwards arrow Products, have rate constants k,4 and kB at temperature T and activation energies EA and EB respectively. If kA > kB and EA < EB and assuming that A for both the reactions is same, then:

  1. at higher temperatures k A will. be greater than kB    
  2. at lower temperatures k A and kB will be close to each other in magnitude    
  3. as temperature rises, k A and kB will be close to each other in magnitude    
  4. at lower temperature kB > kA    

The correct answer is: at higher temperatures k A will. be greater than kB
