1. a mountain biker goes for a ride in the desert. the air temperature is 21°c at the start of the ride, but the temperature in the desert will reach a peak of 51°c. the tires on the bike hold 15.6 l of nitrogen gas at a starting pressure of 249 kpa. the tires will burst when the internal pressure (pb) reaches 269 kpa. answer the following questions and show your work.
• how many moles of nitrogen gas are in each tire?
• what will the tire pressure be at the peak temperature in the desert?
• will the tires burst at the peak temperature? explain.
• to what pressure should the tire pressure be reduced before starting the ride to avoid bursting of the tires in the desert heat? (assume no significant change in tire volume.)

Be sure to answer all parts. the following equilibrium constants were determined at 1123 k: c(s) + co2(g) ⇌ 2co(g) k'p = 1.30 × 1014 co(g) + cl2(g) ⇌ cocl2(g) k''p = 6.00 × 10−3 calculate the equilibrium constant at 1123 k for the reaction: c(s) + co2(g) + 2cl2(g) ⇌ 2cocl2(g) 4.68 × 10 9 (enter your answer in scientific notation.) write the equilibrium constant expression, kp:
