Test Preparation on IIT-JEE solution Paper-2 (2010)
Plots showing the variation of the rate constant (k) with temperature (T) are given below. The plot that following Arrhenius equation is-
K = Ae-Ea/RT
Rate constant K increases exponentially with the rise in temperature. Since rate const. K also depends upon orientation factor A hence its maximum value is not at all infinity rather limited to an optimal value.
The species which by definition has ZERO standard molar enthalpy of formation at 298 K is-
Bromine and water exist in liquid state at 298 K. Methane is not an elemental species.
The correct structure of ethylenediaminetetraacetic acid (EDTA) is-
Based on facts
The bond energy (in kcal mol–1) of a C—C single bond is approximately
C – C single bond dissociation energy ranges between 88 to 150 K cal mol–1.
