The linear form of the Arrhenius equation is very useful as it allows us and the _____ from the intercept. frequency factor, activation energy initial concentration, activation energy activation energy, Boltzmann constant transition state, steric factor Given the following data for the reaction A rightarrow B, determine the activation energy significant figures. 54.4 J/mol 6.89 J/mol 39.9 J/mol 57.3 J/mol 374 J/mol Given the following data for the reaction A rightarrow B, determine the activation energy, A, of the reaction to three significant figures. +1.90 +0.288 _0.643 _0.751 -0.288 The reaction NO_2(g) + CO(g) rightarrow NO(g) + CO_2(g) is thought to occur by the following mechanism: Step 1: NO_2(g) +NO (g) rightarrow NO_3(g) + NO(g) Step 2: NO (g) + CO(g) rightarrow NO_2(g) + CO_2(g) which of the following species is an intermediate? NO_2 NO NO_3 CO_2 This mechanism has no intermediates. This mechanism for the reaction 2 H_2O_2(aq) rightarrow 2 H O() + O_2(g) in the presence of I^-(aq) is proposed to be: Step 1: H_2O_2(aq) + I^-(aq) rightarrow H_2O(l) + OI^-(aq) (slow) Step 2: H_2O_2(aq) + Ol^-(aq) rightarrow H_2O_2(l) + O_2(g) + I^-(aq) (fast) What the molecularity of the rate-determining step? zeromolecular unimolecular bimolecular termolecular More information is needed to answer this question.Explanation / Answer
52.Arrhenius equation is a formula which is used for the temperature dependence of reaction rates.
The equation is given by
k= Ae-Ea/(RT)
k is the rate cinstant
T is the absolute temperature in kelvin
A is pre exponential factor which defines the rate due to collision frequency.
Ea is the activation energy
R is universal gas constant.
The linear plot of this equation allows to calculate activation energy from the slope And frequency factor from the intercept ( option C )
