if reaction is at equ. then adding product will cause reaction to proceed forward and product will increase and removing product will do the same while removing reactant will cause reactn 2 proced bakward and reactant will increase and adding product wl do the same it is in accordnc wth LeChateliars principle
The concentration or activity of the product(s) will increase, and if there is at least one other reactant than the added one that is required for the completion of the reaction, the concentration of such an unadded reactant will decrease. (If there were no available unadded reactant, the reaction would not technically have been in equilibrium at the start, even though it may have reached a steady state that can persist for a long time in the absence of changed conditions.)
Q indicates wether or not a reaction will occur when the value of Q is compared to the equilibrium constant K if Q is larger than K the reaction will occur from product to reactant (decomposition) if Q is smaller than K the reaction will occur from reactant to product
The ratio of product to reactant is dependant on many different things, from the reactants and products themselves to the pressure, temperature and other parameters of the reaction conditions such as the presence of a catalyst. Some reactions are product favoured by nature and at room temperature and 100kPa will always lie at the product side of the equilibrium at STP. Others, like the Haber Process, are reactant favoured and, without manipulation, will produce very little product. To maximise the product it must be made thermodynamically and entropically favourable for it to do so.
Increasing reactant concentration typically leads to an increase in the rate of reaction. This is because there are more reactant molecules available to collide and react with each other. However, this effect is dependent on the overall reaction mechanism and may not always hold true.
If the added substance is a reactant, the equilibrium shifts toward products. If it is a product, it moves towards reactants.
Yes, you can calculate an equilibrium constant for a reaction involving a colored reactant. As long as the reaction is at equilibrium, the equilibrium constant can be determined using the concentrations of reactants and products. The color of a reactant does not prevent the calculation of an equilibrium constant.
The concentration or activity of the product(s) will increase, and if there is at least one other reactant than the added one that is required for the completion of the reaction, the concentration of such an unadded reactant will decrease.

One can determine if a reaction is product-favored or reactant-favored by comparing the equilibrium constant, K, to 1. If K is greater than 1, the reaction is product-favored, meaning more products are formed. If K is less than 1, the reaction is reactant-favored, meaning more reactants are present at equilibrium.
Q indicates wether or not a reaction will occur when the value of Q is compared to the equilibrium constant K if Q is larger than K the reaction will occur from product to reactant (decomposition) if Q is smaller than K the reaction will occur from reactant to product
The equilibrium of the system will be upset.

The reactant was so minimal that it was very hard to notice by the students. Reactant is the change that something goes through.
When the limiting reactant is completely used up. A limiting reactant is the reactant that determines the amount of product. To determine this use the balanced chemical reaction with the masses of the reactants to determine the moles of product formed. The reactant that forms the least amount of product will be the limiting reactant.
Equilibrium is pushed to the reactant side
At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. The concentrations of reactants and products remain constant over time. The equilibrium constant, which is the ratio of product concentrations to reactant concentrations, is constant at a given temperature.
It tells whether products or reactants are favored at equilibrium
