Can rate of reaction be negative?
As far as I know, No. A negative order means a higher concentration of the reactant having a lower reaction rate. For example: concentration of A reaction rate ---- 4 M .1 M/s 1 M .4 M/s ---- rate1/rate2=k(A1)n/k(A2)n k canceled (.1M/s)/(.4M/s)=(4M/1M)n 1/4=4n n=-1 but the reaction rate is usually proportional to the concentration of the reactant, which means reactants with a higher concentration have a greater reaction rate, in a few case, increase the concentration of reactant have little effect for the reaction rate. So, the order of the reaction is usually positive in a few case, it's close to 0.

How can we prepare 1M solution of NaCl?
You could titrate equal volumes of 1M solution of NaOH and 1M solution of HCl to obtain 1M solution of NaCl.
How do you use dimensional analysis to convert between units?
In order to use dimensional analysis, you need to multiply the conversion factor between both units you are trying to convert to by your original value. If you want to convert 24.00m into feet, you multiply this value my the conversion factor. In this case, 1m=3.281ft, or (3.281/1m)=1 as they are equivalent. You also want to have your original unit on the bottom of the ratio so they cancel out. 24.00m x (3.281ft/1m) = 78.744ft The meters cancel as there is one in the nominator of the first number and one in the denominator of the second ratio. If you want to go from feet to meters, the same technique is applied, but the values of the ratio are switched 34ft x (1m/3.281ft) = 10.36m
How many meters is 800 centimeters?
1m = 100cm 800cm x (1m/100cm) = 8m
How many meters are in 4200 millimeters?
1m = 1000mm 4200mm x 1m/1000mm = 4.2m

For the reaction A to Products successive half lives are observed to be 10 min and 40 min A was 0.10 M at the beginning of the reaction What is the integrated rate law and what is the rate constant?
Half-life in this context is defined as the time needed to observe the halving of the original reactant concentration. As you can see, in this case that time doubles each time, so you can say that this particular reaction as a second order rate. The equation for this half-life is: t(1/2) = 1/([A]0 * k) and the integrated rate eq. is: 1/[A] = 1/[A]0 + kt Using the first half life we can calculate k: k = 1/( t(1/2) * [A]0) = 1/(10 min * 0.50 M) = 0.2 min^-1M^-1 Using this value we can calculate the answers for a) and b) a) 1/[A] = 1 / [A]0 + kt = 1 / 0.50 M + .2 min^-1M^-1 * 80 min = 18 M^-1 [A] = 0.056 M b) 1/[A] = 1 / [A]0 + kt = 1 / 0.50 M + .2 min^-1M^-1 * 10 min = 4 M^-1 [A] = 0.25 M

What is larger 1m or 990 cm?
1m = 100cm 990cm/100cm/m = 9.9m 9.9m > 1m, so 990cm > 1m
