Order of a complex reaction is determined from.

Define order of a reaction.

From the rate expression for the following reactions, determine their order of reaction and the dimensions of the rate constants. 3 NO(g) rarr N_2O(g) Rate = k[NO]^2

From the rate expression for the following reactions, determine their order of reaction and the dimensions of the rate constants. CH_3CHO(g) rarr CH_4(g) + CO(g) Rate = k[CH_3CHO]^3/2

From the rate expression for the following reactions, determine their order of reaction and the dimensions of the rate constants. C_2H_5Cl(g) rarr C_2H_4(g) + HCl(g) Rate = k[C_3H_5Cl]

From first order kinetics. We can write [R]=[R]_0e^(-kt) . Draw the graph the [R] against 't'. Why [R] can not be zero? How instantaneous rate is determined form the plot?

The following reaction takes place in one step. 2NO(g)+O_2(g) harr2NO_2(g) How will the rate of the above reaction change if the volume of the reaction vessel is diminished to one third of its original volume? Willthere be any change in the order of the reaction with the reduced volume?

Can order of a reaction be fractional? Comment.

State the role of activated complex in a reaction and state its relation with activation energy.

Show that for a first order reaction the time required for 75% completion is twice the time required for the completion of 50% of reaction.

For a first order reaction, show that time required for 99% completion is twice the time required for the completion of 90% of reaction.
