According to le châtelier's principle, a system at equilibrium will respond to a stress by shifting in the direction that relieves the stress. chemical reactions can be displaced from their equilibrium positions not only by adding or removing reactants or products but also by changing the volume or temperature. changes in volume affect the value of the reaction quotient, q, whereas temperature changes affect the value of the equilibrium constant, k. part a for the following systems at equilibrium a: b: 2nocl(g)h2(g)+i2(g)⇌⇌ 2no(g)+cl2(g)2hi(g) classify these changes by their effect. drag the appropriate items to their respective bins. view available hint(s) leftward shift no shift rightward sh

Listen base your answer to the question on the information below. propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below. c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol. what is the correct structural formula for a molecule of methanethiol
