And equilibrium is specified when the forward rate of reaction is equal to the reverse rate of reaction, the quotient of these rates is formalized by the thermodynamic equilibrium constant,

State the difference between a physical change and a chemical change, and list three indications that a chemical change has occurred. Which indication is most suggestive of a chemical reaction?
Physical changes are changes in the formation or state of molecules and atoms. The arrangement of the molecules and atoms is different after the change but the chemical composition of...

A chemical reaction is a process that changes some chemical substances into others. What is involved in the process of forming these new chemical substances?
Chemical change is characterized by the formation of new substances, and the making and breaking of strong chemical bonds. Usually this is signalled by a colour change, though some few...

You are given 4.5 moles of $O_2$ to react with $1.60 x10^2$ g $C_2H_4$. Upon completion of the reaction, will there be any remaining $C_2H_4$?
We represent the combustion of ethylene by this reaction: $H_2C=CH_2(g) +3O_2(g) rarr 2CO_2(g) + 2H_2O(l)$ For complete combustion, $28*g$ of ethylene thus requires $96*g$ of dioxygen. Here, $"moles of ethylene"$...

How do you calculate the partial pressure of ammonia in the container after the reaction has reached completion? How do you calculate the volume of the container after the reaction has reached completion?
Step 1: Identify the limiting reactant We can use partial pressures as a replacement for moles because $P ∝ n$. $color(white)(mmmmmm)"N"_2color(white)(m) + color(white)(m)"3H"_2 → "2NH"_3$ $P"(atm):"color(white)(mll) 2.73color(white)(mmm)2.73$ $"Divide by:" color(white)(mll)1color(white)(mmmml)3$...

A 0.2 mol sample of N2 , CO2 with a pressure of 840 torr is exposed to solid CaO which react with theCO2 to form solidCaCO3 assume the reaction goes to completion complete pressure the gas had dropped to 320 how many moles of CO2 in origin mixtur?
how
The total pressure in a gas is the sum of the partial pressures of the components, that, at the same temperature and constant volume, are proportional to the molar fractions...

For first degree equation , time for 75% completion of reaction is X times half time of that reaction , where X is ?
As you know, the rate of a first-order reaction depends linearly on the concentration of a single reactant. The of a first-order reaction that takes the form $color(blue)(A ->...

If the rate constant is $3.5 xx 10^(-3) "s"^(-1)$ for a first order decay of reactant $A$, how long does it take the reaction to get to $24%$ completion?
I got about $"78 s"$. $A)$ is incorrect because it is merely one over $k$. $B)$ is incorrect because it results from taking $24%$ completion to mean $24%$ of reactant...

A certain reaction follows zero-order kinetics. Suppose the reaction went to $50%$ completion after $10$ minutes. What percentage of completion does the reaction reach in an additional $5$ minutes?
"Zero order" kinetics means that the rate = k and is independent of the amount of material present. Thus, if the rate is such that the reaction is 50% complete...

For the equilibrium reaction X + y -> XY, the rate of the forward reaction at equilibrium is equal to 1.75 sec^(-1). What is the rate of the reverse reaction?
For the listed hypothetical reaction Rate (fwd) = $k_"fwd"[X][Y]$ Rate (rev) = $k_"rev"[XY]$ By the 'Law of Mass Action' ... Rate(fwd) = Rate(rev) => $k_"fwd"[X][Y]$ = $k_"rev"[XY]$ =>...

If the equilibrium constant (K) = 100, this reaction favors the (reactants/products) and proceeds (very little/almost to completion).
Equilibrium?
Let's take the general equilibrium reaction: $wA+xBharryC+zD$ In which A, B, C and D are and w,x,y,z are coefficients. To determine the equilibrium constant, we write: $K=([C]^yxx[D]^z)/([A]^wxx[B]^x)color(white)(aaaa)color(white)(color(blue)(1.)/color(blue)(2.)$ The equilibrium constant...
