The rate of reduction of [Co(NH3)5(OH2)]3 by Cr(II) is seven orders of magnitude slower than reduction of its conjugate base, [Co(NH3)5(OH)]2, by Cr(II). For the corresponding reductions with [Ru(NH3)6]2, the two differ by less than a factor of 10. What do these observations suggest about their mechanisms?

Suppose you are considering an investment in two bonds. Bond A has a duration of eight years and a market price of $950, and a bond B has a duration of four years and a market price of $1050. How should you invest $10 000 in these bonds if you have a desired holding period of seven years and wish to minimise interest rate risk?

Five people on the basement of a building get on an elevator that stops at seven floors. Assuming that each has an equal probability of going to any floor, find

(b) the probability that two people get off at the same floor and all others get off at different floors. (4 POINTS)

. Suppose that an investor with a five-year investment horizon is considering purchasing a seven-year 9% coupon bond selling at par. The investor expects that he can reinvest the coupon payments at an annual interest rate of 9.4% and that at the end of the investment horizon two-year bonds will be selling to offer a yield to maturity of 11.2%. What is the five-year total return for this bond?

Factory Overhead Budget
Service Department 1 handles personnel matters. The firm anticipates having 12 factory employees and expects the variable costs to operate the personnel department to average $1,000 per employee. The cost of this department is allocated to other departments on the assumption that there will be three employees in the maintenance department, five employees in the molding department, and four employees in the smoothing department. The personnel department’s fixed
costs are estimated to be $15,000 and will be allocated on a lump sum basis at $3,000 to maintenance, $6,000 to molding and $6,000 to smoothing.
The maintenance department is budgeted to make 100 service calls during the period, 60 calls for the molding department and 40 calls for the smoothing department. The maintenance manager estimates that it will cost an average of $150 in variable costs per service call. The fixed costs of $14,000 are thought to benefit the two production departments equally.
The molding department is expected to incur $29,000 in variable overhead and $42,000 in fixed overhead. The smoothing department is expected to have $32,000 in variable overhead and $8,000 in fixed overhead.
Management has decided to allocated 60% of the fixed overhead cost of molding to XL1 and 40% to XL2 and split the fixed smoothing costs evenly between the two products. Variable costs will be allocated based on direct labor hours.
