Methane reacts with chlorine to produce methyl chloride and hydrogen chloride. CH4 + Cl2 → CH3Cl + HCl Once formed, methyl chloride can be chlorinated in subsequent reactions to form methylene chloride (CH2Cl2), chloroform (CHCl3) and carbon tetrachloride (CCl4). In a methyl chloride production process a reactor is fed with methane and chlorine in a molar ratio of 5: 1 (methane: chlorine). In the process the chlorine is consumed in its entirety. The selectivity observed in the process is 4...

At 500 °C, hydrogen iodide decomposes according to 2HI(g)↽−−⇀H2(g)+I2(g)2HI(g)↽−−⇀H2(g)+I2(g) For HI(g)HI(g) heated to 500 °C in a 1.00 L reaction vessel, chemical analysis determined these concentrations at equilibrium: [H2]=0.400 M[H2]=0.400 M , [I2]=0.400 M[I2]=0.400 M , and [HI]=3.38 M[HI]=3.38 M . If an additional 1.00 mol of HI(g)HI(g) is introduced into the reaction vessel, what are the equilibrium concentrations after the new equilibrium has been reached? [HI]= [H2]= [I2]= Please help and show work!

Chlorine gas reacts with fluorine gas to form chlorine trifluoride. Cl2(g) + 3 F2(g) --> 2 ClF3(g) A 2.00-L reaction vessel, initially at 298 K, contains chlorine gas at a partial pressure of 337 mmHg and fluorine gas at a partial pressure of 729 mmHg. Identify the limiting reactant and deter- mine the theoretical yield of ClF3 in grams. I got 4.84g ClF3 for this problem, but the textbook answer is 2.84g. Can anyone tell me where I went wrong,...
