One litre each of a Buffer solution is taken in two beakers connected through a salt bridge. Platinum electrode is immersed in each beaker and electrysis is carried out for 10,000 sec. using a current of 9.65 Ampere. The Buffer contain (1)/(3) mole each of Na_(2)HPO_(4) and NaH_(2)PO_(4) Initially. using the given data answer the following. Given: ltbr. pK_(a) (H_(3)PO_(4)) = 4, pK_(a) (H_(2)PO_(4)^(-)) = 7 , pK_(a) (HPO_(4)^(2-)) = 10 log 2 = 0.3, log3 = 0.48 2.303 (RT)/(F) = 0.06 at 298K What is the pH of compartement in which oxidation taken place during electrolysis.

If during the fermentation of sugar solution that is 0.12 M the concentration of sugar is reduced to 0.06 M in 10 h and to 0.03 M in 20 h the order of reaction is

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?

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.

Directions: Read the following information carefully and answer the given question. A word and number arrangement machine when given an input line of numbers rearranges them following a particular rule in each step. The following is an illustration of an input and rearrangement steps. Input: 78 37 59 18 48 97 63 47 Step 1: 09 78 37 59 48 63 47 02 Step 2: 10 09 59 48 63 47 02 01 Step 3: 11 10 09 59 48 02 01 03 Step 4: 12 11 10 09 02 01 03 04 Step 5: 01 02 03 04 09 10 11 12 And step 5th is the last step of the above input as the desired arrangement is obtained. As per the rules followed in the above steps, find out in the following questions the appropriate step for the given input. Input: 87 73 95 81 84 79 36 74 In step 3, which number comes to the left of 79?
