Two objects exert a gravitational force, F, on each other. Match each change in the distance d between the objects or the mass m of one of the objects to its effect on the gravitational force. Each effect may be matched
to more than one change or not be matched at all.

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
