Consider the reaction: $$2NO(g) + O_2(g) \rightleftharpoons 2NO_2(g)$$ Part A A reaction mixture at 175 K initially contains 522 torr of NO and 421 torr of $$O_2$$. At equilibrium, the total pressure in the reaction mixture is 748 torr. Calculate $$K_p$$ at this temperature. Express your answer to three significant figures. $$K_p = 29.4$$ Part B A second reaction mixture at 175 K initially contains 365 torr of NO and 215 torr of $$O_2$$. What is the equilibrium partial pressure of $$NO_2$$ in this mixture? Express your answer in torr to three significant figures. $$P_{NO_2} = $$ torr

DOT raised the speed limit on a particular stretch of road from 55 to 70 MPH. There is a curve on a portion of the road that was designed assuming various poor road conditions using a coefficient of static friction being between the tires and the road surface =0.15. The curve has a radius of 1/4 mile and a bank angle of 2 degrees originally. Is the road safe at the old and new posted speeds? If not, what should the new bank angle be for the road to be safe.
