Answer: 0.0345 sec
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
![Rate=k[H_3PO_4]^2](https://tex.z-dn.net/?f=Rate%3Dk%5BH_3PO_4%5D%5E2)
k= rate constant = 
Expression for rate law for first order kinetics is given by:

where,
k = rate constant
t = age of sample
a = let initial amount of the reactant
a - x = amount left after decay process
for completion of 20 % of reaction



The time taken for the concentration of
to decrease to 20% to its natural value is 0.0345 sec
Rocket launch site would be the controlled variable
As per Le Chatelier's principle, if the equilibrium of a system is disturbed by changes in temperature, pressure, concentration etc then it will shift in a direction to undo the effect of the induced change.
The given reaction is:
CO + 3H2 ↔ CH4 + H2O
In this case, if the rate of the forward reaction is increased then more of the reactants get converted into products i.e. concentration of reactants decreases. In order to undo this change, the equilibrium will shift in a direction to produce more reactants i.e. to the left.
Ans: B) faster rate of forward reaction
Answer:
im pretty sure its 2.7 gms
Explanation:
im not for sure tho
Answer:
The answer to your question is 194 g
Explanation:
Molecular mass is the sum of all the masses of the atoms that form a molecule.
In the problem, we have C₈H₁₀N₄O₂ which means
atomic mass number of atoms total
Carbon 12 8 12 x 8 = 96
Hydrogen 1 10 1 x 10 = 10
Nitrogen 14 4 14 x 4 = 56
Oxygen 16 2 16 x 2 = 32
194 g
