Describe the two-part reaction carried out by an amino acyl tRNA
synthetase. Show the reactants, the products, and the energy source
that is used to drive the reaction forward. Show how a tRNA is
finally modified by this reaction.
The reaction of CH4 is carried out at a different temperature
with an initial concentration of [CH4] = 9.9×10−2 M . At
equilibrium, the concentration of H2 is 2.0×10−2 M

The gas phase
reaction
2A + B →2C
is
carried out isothermally
and isobarically. The
reaction is first
order in A
and first order in B. The feed is equal molar in
A and B and the entering concentration of A is 0.5 mol/dm3. The
specific reaction rate is k = 4.0 dm3/mol s.
Write
the rate of
reaction, –rA,
solely as a
function of conversion,
evaluating all parameters.
