Wierd lab question
« on: May 09, 2006, 10:22:44 AM »
I'm doing a lab on how temperature effects the rate of a chemical reaction. I have a table of several temperature: time values. One of the questions asks the following:
"Use your results [the table] to calculate by what factor the time for the reactions changes for each 10°C increase in the temperature. (calculate 1/time for each temperature, and then divide the 1/time value at the lower temperature into the 1/time value at the higher temperature)"
I would think I am simply supposed to divide the time for the a temperature by the time for a temperature 10°C higher.. and i should get the same value for each one, but these 1/times confuse me. Do they want me to get the inverse of the answer would normally get or.. help?

1/time simply means one divided by time or time-1. For example, if you had a time of 2 seconds the 1/time would be 1/2 or .5.

if you need further help then a copy of that table might be nice.

1/t is basically the rate of the reaction.

All you are really doining is comparing the rate at different temperatures.
There is no science without fancy, and no art without facts.
