where, k is rate constant and A is the reactant. Answer and Explanation:1 We are given that 75% of a second order reaction is completed in 15 s. To find the half-life of the reaction, we must calculate the rate constant and......
For Exercise, find the constant of variation and write the variation equation. Then use the equation to complete the table or solve the application.p varies directly with the square of q; p = 280 when q = 50 相关知识点: 试题来源: 解析 k=0.112; p=0.112q^2反馈 收藏 ...
The van der Waals’ equation is ( p + (n^(2)a)/(V^(2))) (V-nb) = nRT rArr a = (V^(2))/(n^(2)) [(nRT)/(V- nb) - p] = ((4)^(2))/((2)^(2)) [(2 xx 0.082 xx 300)/(4 - 2 (0.05)) -11] = 6.46atm L^(2) mol^(-2)
Find the value of k for which the constant function x(t) = k is a solution of the differential equation 2t^3(dx/dt) - 2x + 5 = 0. If y=e^{2t} is a solution to the differential equation d^2y/dt^2 - 7dy/dt + ky =0, find the value of th...
aUse the Gibbs-Helmholtz equation to find an expression for d lnxa in terms of dT. Integrate d lnxa from xa=0 to the value of interest, and integrate the right-hand side from the transition temperature for the pure liquid A to the value in the solution. Show that, if the enthalpy ...
The equation of a curve is y =6/(5 - 2x) (i) Calculate the gradient of the curve at the point where x=1.(ii) A point with coordinates (x,y) moves along the curve in such a way that the rate of increase of y has a constant value of 0.02 units per second.Find the rate of...
Another limitation was the low response rate to the school recruitment. Plausibly, for most schools committing to our study towards the last months of the school year would conflict with a compressed school agenda upon the reopening year. Next, we conducted this research in an area where schools...
By adjusting a few axis format variables in Excel, we can simply plot a log-log graph. Both axes in the log-log or natural log-log graph are really on a logarithmic scale. Similar to the equationy = c. xa, this graph illustrates whether the variables are in a constant power relationsh...
“home-free,” because I broke free from the shackles of homeownership — the yard work, the constant repairs, the mortgage and property tax payments. In fact, a lot of the reason that I chose to become full-timers had to do with my very flawed decision to buy a house. Homeownership ...
LASSO presents the regression coefficients𝛽𝑘βk(Equation (1)) as a function of a regularization parameter Lambda (λ), which determines the influence of the classical least squares contribution (first sum over n in Equation (2)) relative to the sum of modulus of the coefficients (second ...
