The energy of activation of a first order reaction is 187.06 kJ mol^(-1) at 750 K and the value of pre-exponential factor A is 1.97xx10^(12)s^(-1) . Calculate the rate constant and half life. (e^(-30)= 9.35xx10^(-14))

In a reaction with initially 0.12 M , the concentration of reactant is reduced to 0.06 M in 10 hour and to 0.03 M in 20 hour. (i) What is order of reaction? (ii) What is rate constant? (b) The rate of a first order reaction is 0.04 mol litre^(-1) s^(-1) at 10 minute and 0.30 mol litre^(-1) at 20 minute after initiation. Find the half-life of the reaction.

II. Read the following passage and answer questions 6-10 that follow : During organic reactions, a covalent bond between two carbon atoms or carbon atom and some other atom is broken and a new bond is formed. The fission of bonds can be homolytic or heterolytic forming free radicals, carbocations carbanions, carbenes, etc. This also depends upon the displacement, of electron in a bond and is governed by inductive effect, electromeric effect, reasonance and hyperconjugation. Complete the reaction : CH_2 N_2 overset("Light") (to) and name the species formed.

Agrabah, the city of mystery, enchantments and the finest merchandise located on the side of the river Jordan. It is under the rule of the king named Sultan. Aladdin lives in a hovel with his monkey Abu where he has spent most of his childhood. Now it’s time to explore more about this mysterious city! Festival season is going in Agrabah and the people are going crazy to see various sorcerers, craftsmen etc. who are visiting the city to showcase their magic. A large crowd has gathered around a Card-master who is asking a logical riddle to the crowd. Whosoever succeeds in solving the riddle gets a reward. He arranges the cards of first 20 natural numbers and lists down the difference between two consecutive numbers (value on right card minus value on the left card) of the arrangement, which are 19 in number. The difference is given as -11 8 -7 -2 11 -4 12 -15 11 3 -13 9 -1 -3 6 -10 -3 5 9 What is the first number of his arrangement of cards from the left?

If the fermentaion of sugar in an enzymatic solution that is 0.12 M, the concentration of the sugar is reduced to 0.06 M in 10 h and to 0.03 M in 20 h. What is the order of the reaction?
