rate is first-order, and the lab constant is given by the expression k = (3.8 x
10^14 s-1)e-229000/RT, where the activation energy is in J mol-1. Calculate the
temperature at which (a) ethyl bromide decomposes at the rate of 1% per
second and (b) the decomposition is 70% complete in 1 hour.
compound initially at 55.5 kPa was 340 s. When the pressure was 28.9 kPa, the
half-life was 178 s. Determine the order of the reaction.
Q4. When the skeleton oxidation-reduction equatioт is balanced in ACIDIC solution using the smallest whole number coefficients, the coefficient of Br- is: *
ADP was far in excess of the enzyme concentration for all of the measurements.
The relaxation effect was assumed to arise from a conformational change in the enzymeADP complex.
E+ADP to (EADP)1, equilibrium constant K1
Then, (EADP)1 to (EADP)2, equilibrium constant K2
(EADP)2 to (EADP)1, equilibrium constant K-2
which follows the rapid equilibrium of enzyme-ADP complex formation.
The first step is considered to be in equilibrium on the time scale of the conformational change. Thus, write down the expression for the equilibrium constant K1, rearrange to get [E] alone on the left hand side and differentiate with respect to EADP1 to arrive at an expression relating ΔE to Δ(EADP)1. Because ADP was in excess, you can assume that [ADP] is a constant.
