For each of the following data sets find the range and the standard deviation. a) The measured concentration of a sodium hydroxide (NaOH) solution: 0.01003, 0.01002, 0.00993, 0.01019, and 0.01008 M.
b) The percentage of iron determined to be in an ore sample: 21.7, 18.3, 17.0, and 20.0%.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

the correct answer would be b) volume versus temperature, because they are also directly proportional.
