Catalysed Reaction

Consider the following reactions at 300 K. A rarr B (uncatalysed reaction) Aoverset("catalyst")rarrB (catalyst reaction) The activation energy is lowered by 8.314"KJ mol"^(-1) for the catalysed reaction. How many times the rate of this catalysed reaction greater than that of uncatalysed reaction?(Given e^(3.33)=20)

Show that the maximum enzyme catalysed reaction rate will occur for [H^(+)]_("opt")=sqrt(k_(1)k_(2) The general pH control enzyme catalysed reaction is EH_(2)^(2+) hArr EH^(+) hArr E Only EH^(+) is capable for binding substrate and catalysing the desired reaction, k_(1)=([EH^(+)][H^(+)])/([EH_(2)^(2+)]), k_(2) =([E][H(+)])/([EH^(+)]

Given that the normal energy of the reactant and produce are 40J and 20 J respectively and threshold energy of the uncatalysed reaction is 120 J.If the rate of uncatalysed reaction at 400 K becomes equal to the rate of catalysed reaction at 300 K, then what will be the activation energy of the catalysed forward and backward reactions respectively ?

The base catalysed reaction of 1,2-diketone to a salt of 2-hydroxy carbonxylic acid is known as benzile acid rearrangement . The reaction is not application to 1,2-diketones containing alpha- methylene group because of competing aldol condensation .

Statement-1 : The catalyst does not affect the equilibrium constant. Statement-2 : Because for the catalysed reaction and uncatalysed reaction Delta H remains same and equilibrium constant depends on Delta H .

Assertion : Co-enzymes serves as co-factors in a number of differen enzymes catalysed reaction. Reason : Association of co-enzyme with the apoenzyme is only transient, usually occurring during the course of catalysis.

Enzymes which catalyse reaction involving change in the structure of a molecule are
