The reaction of thioacelamidc with water is shown by the equation below: CH 3 C ( S ) NH 2 ( a q ) + H 2 O → H 2 S ( a q ) + CH 3 C ( O ) NH 2 ( a q ) The rate of reaction is given by the rate law: Rate = k [ H 3 O + ] [ CH 3 C ( S ) NH 2 ] Consider one liter of solution that is 0.20 M in CH 3 C(S) NH 2 and 0.15 M in HCl at 25°C. a For each of the changes listed below, state whether the rate of reaction increases, decreases, or remains the same. Why? i. A 4-g sample of NaOH is added to the solution. ii. 500 mL of water is added to the solution b For each of the changes listed below, state whether the value of k will increase, decrease, or remain the same. Why? i. A catalyst is added to the solution. ii. The reaction is carried out at 15 o C instead of 25°C.

Suppose the rate of evaporation in a hot, dry region is 1.76 meters per year, and the seawater there has a salinity of 35 ‰. Assuming a 93% yield, how much salt (NaCl) can be harvested each year from 1 km2 of solar evaporation ponds that use this seawater as a source?
