The decomposition of AB_2 to AB and B is first-order with k = 2.8 xx 1

1.	The decomposition of AB_2 to AB and B is first-order with k = 2.8 xx 10^(-7)s^(-1) at 1000^@CAB_2 to AB + BAtomic weights of A and B are 12 and 32 respectively.(i) Find the half-life of this reaction at 1000^@C.(ii) How many days would pass before 1 g of AB_2 had decomposed to theextent that 0.60 g of AB_2remained? (iii) With reference to (ii), how many grams of AB would be present after this length of time?(iv) How much of a 1-g sample of AB_2would remain after 35 days?
Answer» SOLUTION :28.58 DAYS, 20.84 days, 0.23 G, 0.43 g
