Answer:

True

Explanation:

When determining rate law, the coefficients in the balanced equation are used to determine how different concentrations affect the rate.

A gas in a piston–cylinder assembly undergoes a compression process for which the relation between pressure and volume is given

m_a_m_a [10]

Answer:

1.

$A=69.8\frac{bar}{m^6}\\\\ B=0.00302bar*m^6$

2. $W=-8.2kPa$

Explanation:

Hello,

1. In this case, for the given p-V equation, one could use the two states to form a 2x2 linear system of equations in terms of A and B:

$\left \{ {{0.1^2A+0.1^{-2}B=1} \atop {0.04^2A+0.04^{-2}B=2}} \right.$

$\left \{ {{0.01A+100B=1} \atop {0.0016A+625B=2}} \right$

Whose solution by any method for solving 2x2 linear system of equations (elimination, reduction or substitution) is:

$A=69.8\frac{bar}{m^6}\\\\ B=0.00302bar*m^6$

2. Now, for us to compute the work, we must first compute n, as the power relating the pressure and volume for this process:

$P_1V_1^n=P_2V_2^n\\\\\frac{P_1}{P_2}=(\frac{V_2}{V_1} )^n\\\\\frac{1bar}{2bar}= (\frac{0.04m^3}{0.1m^3} )^n\\\\0.5=0.4^n\\\\n=\frac{ln(0.5)}{ln(0.4)} =0.7565$

Now, we compute the work:

$W=\frac{P_2V_2-P_1V_1}{1-n} =\frac{2bar*0.04m^3-1bar*0.1m^3}{1-0.7565} \\\\W=-0.082bar*m^3*\frac{1x10^2kPa}{1bar}\\ \\W=-8.2kPa$

Regards.

Is there a mathematical pattern in the number of

aleksandrvk [35]

Answer:

The orbital shapes are actually representation of (Ψ)2 all over the orbit simplified ... ψnlml(r,θ,ϕ)=Rnl(r)Ymll(θ,ϕ) , ... and thus it is directly linked to the angular and radial nodes. ... for different quantum values(which can be assigned to different orbitals are ) .... The two types of nodes are angular and radial.
