Both capacitors have accumulated a certain amount of charge (and it does not matter if the corresponding voltages are different). If both capacitors act in parallel (one side grounded and the other side connected to the inverting opamp terminal which is on virtual ground) the charge is transferred completely (opamp ideal) to the feedback capacitor.

The farads (called the capacitance) are a geometric property of the capacitor that tells you how much charge you can store in the capacitor with a given voltage. These properties are related by the following equation V=Q/C or voltage = charge/capacitance. Once you attach a voltage source to the capacitor it fills with as much charge as it can.

Learn More(Thanks Neil for pointing this out) When 2 capacitors are connected in parallel, the voltage rating will be the lower of the 2 values. e.g. a 10 V and a 16 V rated capacitor in parallel will have a maximum voltage rating of 10 Volts, as the voltage is the same across both capacitors, and you must not exceed the rating of either capacitors.
When 4, 5, 6 or even more capacitors are connected together the total capacitance of the circuit CT would still be the sum of all the individual capacitors added together and as we know now, the total capacitance of a parallel circuit is always greater than the highest value capacitor.
which means that the equivalent capacitance of the parallel connection of capacitors is equal to the sum of the individual capacitances. This result is intuitive as well - the capacitors in parallel can be regarded as a single capacitor whose plate area is equal to the sum of plate areas of individual capacitors.
The voltage ( Vc ) connected across all the capacitors that are connected in parallel is THE SAME. Then, Capacitors in Parallel have a “common voltage” supply across them giving: VC1 = VC2 = VC3 = VAB = 12V In the following circuit the capacitors, C1, C2 and C3 are all connected together in a parallel branch between points A and B as shown.
One example are DC supplies which sometimes use several parallel capacitors in order to better filter the output signal and eliminate the AC ripple. By using this approach, it is possible to use smaller capacitors that have superior ripple characteristics while obtaining higher capacitance values.
CpV = C1V + C2V + C3V. This equation, when simplified, is the expression for the equivalent capacitance of the parallel network of three capacitors: Cp = C1 + C2 + C3. This expression is easily generalized to any number of capacitors connected in parallel in the network.
