What is the rate constant of a first-order reaction that takes 536 seconds for the reactant concentration to drop to half of its initial value? Express the answer with the appropriate units. Rate of Reaction: The rate of a rea...
The rate constant of a first order reaction is2.31×10−2s−1. What will be the time required for the initial concentration, 0.1M, of the reactant to be reduced to 0.05 M? View Solution The rate constant for a first order reaction is4.606×10−3s−1. The time required to reduce...
Reason (R) This reaction proceeds through the formation of a carbocation. View Solution On increasing the temperature , the rate of a reaction: View Solution The reaction proceeds by the mechanism View Solution The rate constant of a reaction is equal to the rate of reaction when ...
Extrapolation to a wider temperature range through ab initio calculations yields the rate constant k 1 = 3.6 × 10 4 T 2.5 exp ( - 14 425 [ K ] / T ) cm 3 mol - 1 s - 1 . The reaction is probably of minor importance in combustion. The present analysis reconciles the batch ...
Rate constantActivation energyReaction F + CH4 → HF + CH3 (1) has been studied using a discharge flow reactor combined with mass spectrometry in the temperature range 220 – 960 K. The rate constant of the reaction was determined using both absolute and relative rate measurements: k1 = (...
