Consider the following reaction: cus(s) + o2(g) ↔ cu(s) + so2(g) a reaction mixture initially contains 2. 9 m o2. Determine the equilibrium concentration of o2 if kc for the reaction at this temperature is 1. 5.

The distance d that a car can travel in a certain amount of time t can be found by multiplying the rate of speed r by the travel time. if a car has already travel 4 miles, the formula for the total distance travel is d= rt + 4. which of the following gives the value of r, in terms of d and t?
