A 50-mL Mohr buret is connected to a 1-ft length of capillary tubing. The buret is then filled with water and the volume of water versus time is monitored as the water gradually flows through the capillary tubing.

Question

This process is found to be first-order with a rate constant of 0.014 mL/sec. What will happen if the length of the capillary tube is doubled?

a)The process will still be first-order, but the rate constant will decrease.

b)The order and rate constant for the process will both change.

c)The order of the process will change, but the rate constant will be constant.

d)The process will still be first-order, but the rate constant will increase.

I know the answer's not C for sure and if there's a choice E then it's not that either

Hmm · Answer

It will still be first order but the constant will decrease.
