The rate of a reaction quadruples when the temperature changes from 293 K to 313 K. Calculate the energy of activation of the reaction assuming that it does not change with temperature.
The time required for 10% completion of a first order reaction at 298 k is equal to that required for its 25% completion at 308 K. If the value of A is 4 × 1010 s-1, Calculate k at 318 k Read More …
The decomposition of A into product has value of k as 4.5 × 103 s-1 at 10°C and energy ofactivation 60 kJ mol-1. At what temperature would k be 1.5 × 104 s–1?
The rate constant for the first order decomposition of H2O2 is given by the following equation: log k = 14.34 – 1.25 × 104 K/T. Calculate Ea for this reaction and at what temperature will its half-period be 256 minutes?
