Experiment: Group 1 drinks 500 mL of coffee a day, group 2 drink 500 mL of tea a day, group 3 is a control group. At the end of 60 days all participants’ blood pressure is tested. Write a scientific question for the experiment. Be sure to include the independent and dependent variable in your question.

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
