Answer: The amount of water produced is 9.3 grams
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
mass of reactants = mass of methane + mass of oxygen = 22.5 g + 35.7 g = 58.2 g
mass of products = mass of carbon dioxide + mass of water = 48.9 g + mass of water
48.9 g + mass of water = 58.2 g
mass of water = 9.3 g
Complete Question
The rate of a certain reaction is given by the following rate law:
rate Use this information to answer the questions below.
What is the reaction order in ?
What is the reaction order in ?
What is overall reaction order?
At a certain concentration of H2 and I2, the initial rate of reaction is 2.0 x 104 M / s. What would the initial rate of the reaction be if the concentration of H2 were doubled? Round your answer to significant digits. The rate of the reaction is measured to be 52.0 M / s when [H2] = 1.8 M and [I2] = 0.82 M. Calculate the value of the rate constant. Round your answer to significant digits.
Answer:
The reaction order in is n = 1
The reaction order in is m = 1
The overall reaction order z = 2
When the hydrogen is double the the initial rate is
The rate constant is
Explanation:
From the question we are told that
The rate law is
The rate of reaction is
Let the reaction order for be n and for
be m
From the given rate law the concentration of is raised to the power of 1 and this is same with
so their reaction order is n=m=1
The overall reaction order is
At
= >
given that the concentration of hydrogen is doubled we have that
=>
So equating the two k
=>
So when
We have
