Answer : The value of is -166156 J and equilibrium composition should favor products at standard conditions.
Explanation :
Now we have to calculate the Gibbs free energy.
As we know that,
where,
= standard Gibbs free energy = ?
= standard enthalpy = -249 kJ = -249000 J
= standard entropy = -278 J/K
T = temperature of reaction =
Now put all the given values in the above formula, we get:
- A reaction to be spontaneous when and reaction will be favored in the forward direction that means favored in products.
- A reaction to be non-spontaneous when and reaction will be favored in the backward direction that means favored in reactants.
As the value of is less than zero that means the reaction is spontaneous and reaction will be favored in the forward direction that means favored in products.
Hence, the value of is -166156 J and equilibrium composition should favor products at standard conditions.
Answer:
The acceleration of the car at the instant when t=3s is found by taking the gradient of the tangent at the point t=3.
The tangent are those dotted lines sloping upwards in the graph.
Tangent: A straight line that touches the curve and does not intersect it.
The reason why they wrote instantaneous is because the acceleration (or gradient of graph) is not constant throughout hence it is just at the moment when t=3s.
Gradient is used to find the acceleration of a speed time graph.
I would say C.
Developing a plan is important because it will motivate you and tell you when to get things done. It is the most efficient
Hope this helped :)
